The contribution to the chi-square test statistic for men who selected business networking as the most important factor is 0.001. To calculate the contribution to the chi-square test statistic for men who selected business networking as the most important factor, we need to use the formula:

Contribution = (Observed frequency - Expected frequency[tex])^2[/tex]/ Expected frequency

where the expected frequency is the total number of men (1990) multiplied by the proportion of men who selected business networking as the most important factor (0.0225):

Expected frequency = 1990 x 0.0225 = 44.775

The observed frequency is 45 (from the table). Substituting these values into the formula, we get:

Contribution = (45 - 44.775[tex])^2[/tex] / 44.775 = 0.001

So the contribution to the chi-square test statistic for men who selected business networking as the most important factor is 0.001.

Using implicit differentiation to find y'. Then evaluate y' at (2,0). 16e^Y = x^4 - y^3 y', y'(2,0) = 2

Given the equation: 16e^Y = x^4 - y^3, we want to find y' (the derivative of y with respect to x) using implicit differentiation and then evaluate y' at the point (2,0).

Step 1: Differentiate both sides of the equation with respect to x.
d/dx(16e^Y) = d/dx(x^4 - y^3)

Step 2: Apply the differentiation rules (chain rule for e^Y term and power rule for x^4 and y^3 terms).
16e^Y(dy/dx) = 4x^3 - 3y^2(dy/dx)

Step 3: Solve for dy/dx (y').
16e^Y(dy/dx) + 3y^2(dy/dx) = 4x^3
dy/dx(16e^Y + 3y^2) = 4x^3
y' = dy/dx = 4x^3 / (16e^Y + 3y^2)

Step 4: Evaluate y' at the point (2,0).
y'(2,0) = 4(2^3) / (16e^(0) + 3(0)^2)
y'(2,0) = 32 / (16 + 0)
y'(2,0) = 32 / 16
y'(2,0) = 2

So, the derivative y' is given by the formula:
y' = 4x^3 / (16e^Y + 3y^2)

And the evaluated value at point (2,0) is:
y'(2,0) = 2

According to the unitary method, the lab technician can save money by blending 1.09 ounces of food x and 3.91 ounces of food y to meet the rabbits' nutritional needs.

First, let's determine the total minimum amount of each nutrient that the rabbits need per day. According to the requirements, the rabbits need a minimum of 24 g of fat, 36 g of carbohydrates, and 4 g of protein per day. Using a unitary method, we can find out how much of each nutrient is required per ounce of food:

For fat: 24 g ÷ 5 oz = 4.8 g/oz

For carbohydrates: 36 g ÷ 5 oz = 7.2 g/oz

For protein: 4 g ÷ 5 oz = 0.8 g/oz

Now we can compare these requirements to the nutrient content of food x and food y to determine the optimal blend. Let's use the variables x and y to represent the number of ounces of food x and food y, respectively, in the blend. We can set up the following equations:

8x + 12y = 4.8x + 7.2y + 24 (equation for fat)

12x + 12y = 7.2x + 4.8y + 36 (equation for carbohydrates)

2x + y = 0.8x + 0.8y + 4 (equation for protein)

We also know that the total amount of food in the blend should not exceed five ounces, so we can add the following constraint:

x + y ≤ 5 (equation for total food limit)

Now we can solve for x and y by using any method of solving a system of equations. In this case, it's easiest to use substitution. Let's use the equation for protein to solve for y:

2x + y = 0.8x + 0.8y + 4

1.2y = 1.2x + 4

y = x + 3.33

Now we can substitute y in the other equations:

8x + 12(x + 3.33) = 4.8x + 7.2(x + 3.33) + 24

20.67x = 22.62

x ≈ 1.09

12x + 12(x + 3.33) = 7.2x + 4.8(x + 3.33) + 36

21.99x = 26.61

x ≈ 1.21

Therefore, the optimal blend is 1.09 ounces of food x and 3.91 ounces of food y. Let's check if this blend meets the nutritional requirements:

Fat: (8 g/oz x 1.09 oz) + (12 g/oz x 3.91 oz) = 64.28 g > 24 g (minimum required)

Carbohydrates: (12 g/oz x 1.09 oz) + (12 g/oz x 3.91 oz) = 59.28 g > 36 g (minimum required)

Protein: (2 g/oz x 1.09 oz) + (1 g/oz x 3.91 oz) = 5.09 g > 4 g (minimum required)

As we can see, the optimal blend meets all the nutritional requirements and stays within the daily food limit of five ounces. The cost of the blend can be calculated as follows:

Cost of food x: 1.09 oz x $0.20/oz = $0.218

Cost of food y: 3.91 oz x $0.30/oz = $1.173

Total cost: $0.218 + $1.173 = $1.391

The computation of the Hilbert polynomial is a fundamental tool in algebraic geometry that provides important information about the geometry and topology of complex algebraic varieties.

The Hilbert polynomial of a complex algebraic variety X with respect to a very ample line bundle L is a polynomial that encodes information about the dimension and degree of the cohomology groups of X associated with L. More specifically, it is defined as the alternating sum of the dimensions of the cohomology groups of L^k restricted to X, multiplied by appropriate binomial coefficients. In practice, the Hilbert polynomial can be computed using a variety of techniques, including Grothendieck-Riemann-Roch and Serre duality.
One approach involves computing the Chern classes of L and using them to construct the Todd class, which can then be used to compute the Hirzebruch-Riemann-Roch formula. This formula relates the Euler characteristic of the tensor product of L with the tangent bundle of X to the degree and higher cohomology groups of X with respect to L. By manipulating the formula and taking appropriate limits as k approaches infinity, one can obtain the coefficients of the Hilbert polynomial.
Another approach involves computing the Riemann-Roch spaces associated with L, which are vector spaces consisting of sections of tensor powers of L with certain growth conditions at infinity. By studying the dimensions of these spaces and their asymptotic behavior, one can obtain the coefficients of the Hilbert polynomial.
Overall, the computation of the Hilbert polynomial is a fundamental tool in algebraic geometry that provides important information about the geometry and topology of complex algebraic varieties.

The linear approximation of the function at x = 5.1. We can calculate it in the following manner.

To find dy, we first need to calculate f'(x) (the derivative of f(x)):

f'(x) = e^x + xe^x

Now we can plug in x=5 to find f'(5):

f'(5) = e^5 + 5e^5

= 1680.25

Using dx=0.1, we can approximate the change in y (dy) as:

dy = f'(5)dx

= 1680.25 * 0.1

= 168.025

Therefore, when x=5 and dx=0.1, dy = 168.025.

To find the linear approximation using dy, we add dy to f(5):

f(5.1) = f(5) + dy

= (5*e^5) - 5 + 168.025

= 864.025

So the linear approximation using dy is f(5.1) = 864.025.

For the function y = f(x) = x * e^x - 5, we want to find the linear approximation at x = 5 when dx = 0.1.

First, we need to find the derivative f'(x), which represents the slope of the tangent line at any point x:

f'(x) = (x * e^x - 5)'

Using the product rule for derivatives, we get:

f'(x) = (1 * e^x + x * e^x)

Now, we can evaluate f'(5) to find the slope of the tangent line at x = 5:

f'(5) = (1 * e^5 + 5 * e^5) = 6 * e^5

Next, we use the given dx value to approximate the change in y, dy:

dy = f'(5) * dx = (6 * e^5) * 0.1

Now we can find the linear approximation at x = 5.1:

f(5.1) ≈ f(5) + dy

First, calculate f(5):

f(5) = 5 * e^5 - 5

Finally, add dy to f(5) to find the linear approximation:

f(5.1) ≈ (5 * e^5 - 5) + (6 * e^5) * 0.1

This is the linear approximation of the function at x = 5.1.

According to proportion, when y = 42, x = -7.

Proportions are a fundamental concept in mathematics that are used to relate two or more quantities. In this case, if y varies directly with x, it means that y and x are proportional to each other. This means that if one quantity changes, the other changes in the same proportion.

To solve the problem of finding x when y = 42, we can use the proportionality between y and x. This proportionality can be expressed as:

y/x = k

where k is the constant of proportionality. Since we know that y = -36 when x = 6, we can substitute these values into the equation above to solve for k:

-36/6 = k

k = -6

Now that we have the value of k, we can use the equation above to find x when y = 42:

42/x = -6

To solve for x, we can cross-multiply and simplify:

42 = -6x

x = -7

The values of x that satisfy rank(A)=2 are x = -9/10 and all values except x = -9/10. To find all values of x so that rank(A) = 2, we first need to perform row reduction on matrix A:

A = ⎡⎢⎣−210701x910−31⎤⎥⎦
Begin by swapping the first and second rows:
A = ⎡⎢⎣7101x−210−31⎤⎥⎦
Now, divide the first row by 7:
A = ⎡⎢⎣101x/7−3/107/103/10−31⎤⎥⎦
Next, add 2 times the first row to the second row:
A = ⎡⎢⎣101x/7−3/1003/10 + 2x/7−1⎤⎥⎦
In order for rank(A) to be 2, the second row cannot be a multiple of the first row. Thus, the coefficients of x in the second row must not be a multiple of the first-row coefficients.
3/10 + 2x/7 ≠ k(x/7), where k is any scalar multiple.
Multiplying both sides by 70 to eliminate fractions, we get:
21 + 20x ≠ 10kx
Rearrange the equation:
20x - 10kx ≠ -21
Factor out x:
x(20 - 10k) ≠ -21
For the rank to be 2, x cannot be equal to -21/(20 - 10k) for any integer k.
So, the values of x that make rank(A) = 2 are all real numbers except -21/(20 - 10k), where k is any integer.

To find all values of x so that rank(A)=2, we need to perform row operations on matrix A to bring it to reduced row echelon form and count the number of non-zero rows. If the number of non-zero rows is 2, then the rank of A is 2.
Starting with matrix A:
⎡-2  1  0⎤
⎢ 0 -7  1⎥
⎣ 0  9 10x⎦
Performing row operations:
R2 -> R2 + 3/2 R1
R3 -> R3 + 9/2 R1
⎡-2  1    0   ⎤
⎢ 0 -7    1   ⎥
⎣ 0  0  10x+9 ⎦
Now we have three possible cases:
1. If 10x+9 = 0, then the third row is all zeros and the rank of A is 2. Solving for x, we get:
10x+9 = 0
10x = -9
x = -9/10
2. If 10x+9 ≠ 0 and x ≠ -9/10, then the third row is non-zero and the rank of A is 3.
3. If 10x+9 ≠ 0 and x = -9/10, then the third row becomes all zeros and the rank of A is 2.
Therefore, the values of x that satisfy rank(A)=2 are x = -9/10 and all values except x = -9/10.

The probability that a particular lightbulb will last from 2694 to 3583 hours is 0.8425 or 84.25%.

To convert our given data into a standard normal distribution, we will use the z-score formula:

z = (x - μ) / σ

Where:

x is the value we want to convert

μ is the mean of the distribution

σ is the standard deviation of the distribution

In this case, we want to find the z-scores for 2694 and 3583. Using the formula, we get:

z(2694) = (2694 - 2961) / 259 = -1.03

z(3583) = (3583 - 2961) / 259 = 2.41

Now, we need to find the area under the standard normal curve between these two z-scores. We can use a standard normal distribution table or a calculator to find this area.

Using a calculator, we can find the probability that a particular lightbulb will last from 2694 to 3583 hours by finding the difference between the cumulative probabilities of the two z-scores:

P(2694 < x < 3583) = P(-1.03 < z < 2.41) = P(z < 2.41) - P(z < -1.03)

= 0.9918 - 0.1493

= 0.8425

The correct answer is A. The likelihood of picking a daisy at random from Bouquet T is higher than that of selecting a daisy at random from Bouquet S.

What is probability?

Probability is a numerical representation of how likely an event is to happen. The probability ranges from 0, indicating that the event is impossible, to 1, indicating that the event is certain to occur.

To determine the probability of randomly selecting a daisy from each bouquet, we need to know the total number of flowers in each bouquet.

There are 13 daisies in each bouquet, so the probability of randomly selecting a daisy from either bouquet is 13 divided by the total number of flowers in that bouquet.

For Bouquet S, the total number of flowers is 30. Therefore, the likelihood of randomly selecting a daisy from Bouquet S is 13/30.

For Bouquet T, the total number of flowers is 13. Therefore, the probability of randomly selecting a daisy from Bouquet T is 1, since all the flowers in Bouquet T are daisies.

Comparing the two probabilities, we can see that 13/30 is less than 1. So, the correct statement is:

A. The probability of randomly selecting a daisy from Bouquet S is less than probability of randomly selecting a daisy from Bouquet T.

The maximum absolute error using the Remainder Estimation Theorem is 2.061 x 10^-5 (option c).

To estimate the maximum absolute error for the polynomial 1 + 5x + 10x^2 when approximating f(x) = (1 + x)^5 on the interval |x| <= 0.1 using the Remainder Estimation Theorem, follow these steps:

1. Calculate the 4th derivative of f(x) = (1 + x)^5, which is f''''(x) = 120.

2. Determine the maximum absolute value of f''''(x) on the interval |x| <= 0.1. Since f''''(x) is constant, the maximum absolute value is 120.

3. Use the Remainder Estimation Theorem to find the maximum absolute error: |R_n(x)| <= M * |x - a|^4 / 4! where M is the maximum absolute value of f''''(x) on the interval, a is the center of the interval, and n is the degree of the approximating polynomial. Here, n = 2 and a = 0.

4. Calculate the maximum absolute error: |R_2(x)| <= 120 * |x|^4 / 4! = 120 * |x|^4 / 24. Since |x| <= 0.1, the maximum occurs when |x| = 0.1.

5. Compute the maximum absolute error: 120 * (0.1)^4 / 24 = 2.061 * 10^-5.

So, the maximum absolute error using the Remainder Estimation Theorem is 2.061 x 10^-5 (option c).

The complete question is:

Whether or not normal approximation can be used for  number of winning plays depends on sample size, probability of winning, and the distribution of the data. Careful consideration should be given to these factors before using th normal approximation.

The normal approximation can be used when the sample size is large enough and the distribution is approximately normal. In the case of winning plays, it depends on the number of total plays and the probability of winning.
If the number of total plays is large enough, such as in the case of a national lottery with millions of tickets sold, then the normal approximation can be used to estimate the number of winning plays. The probability of winning is usually very low, so the distribution can be approximated as a normal distribution.
However, if the number of total plays is small, such as in the case of a small local raffle, the normal approximation may not be appropriate. In this case, the distribution may not be normal and the sample size may not be large enough to justify the use of the normal approximation.
Additionally, if the probability of winning is very high or very low, the normal approximation may not be appropriate. For example, if the probability of winning is close to 0 or 1, the distribution may be skewed and the normal approximation may not accurately reflect the true distribution.
In conclusion, whether or not the normal approximation can be used for the number of winning plays depends on the sample size, probability of winning, and the distribution of the data. Careful consideration should be given to these factors before using the normal approximation.

The rate of change of the area of the triangle is -49.5 cm^2/s.

In this problem, the base is decreasing at a rate of 11 cm/s and the height is constant at 9 cm. To find the rate of change of the area, we can use the given information:

1. The formula for the area of a triangle is: Area = (1/2) * base * height.
2. The base is decreasing at a rate of 11 cm/s: d(base)/dt = -11 cm/s.
3. The height is constant at 9 cm: height = 9 cm.

Now, we differentiate the area formula with respect to time t:

d(Area)/dt = (1/2) * d(base * height)/dt.

Since the height is constant, we can rewrite this as:

d(Area)/dt = (1/2) * height * d(base)/dt.

Plug in the given values:

d(Area)/dt = (1/2) * 9 * (-11).

There is no smallest counterexample to prove and  6 divides (7ⁿ - 1) for all integers n ≥ 1

To prove that 6 divides (7ⁿ - 1) for all integers n ≥ 1 using the method of smallest counterexamples, follow these steps:

1. Assume there exists a smallest counterexample, let's call it k, such that 6 does not divide (7ᵏ - 1).

This means that 7ᵏ- 1 = 6m + r, where 0 < r < 6 and m is an integer.

2. Now, consider the next power of 7:

7ᵏ+¹ - 1. We want to show that 6 also does not divide this expression, contradicting the assumption that k was the smallest counterexample.

3. Observe that 7ᵏ+¹ - 1 = 7 * (7ᵏ+¹) + (7 - 1).

4. Since 7ᵏ - 1 = 6m + r, we can rewrite the expression as: 7ᵏ+¹ - 1 =

7 * (6m + r) + 6.

5. Simplifying, we get 7ᵏ+¹ - 1 = 42m + 7r.

6. We know that 0 < r < 6 and 7r < 42.

Therefore, 42m + 7r is a multiple of 6, which implies that 6 divides (7ᵏ+¹ - 1).

For any integer m, m² is always congruent to either 0, 1, or 4 modulo 5. Therefore, m² is always of the form 5k, 5k+1, or 5k+4 for some integer k.

The statement is true, and it is known as the Law of Quadratic Reciprocity.

For any integer m, m² is always congruent to either 0, 1, or 4 modulo 5.

That is, m² is always of the form 5k, 5k+1, or 5k+4 for some integer k.

This can be proven using the fact that every integer can be written in one of the forms 5k, 5k+1, 5k+2, 5k+3, or 5k+4 for some integer k.

Squaring each of these forms modulo 5 yields:

(5k)² = 25k² ≡ 0 (mod 5)

The cubic meters of air does the balloon lose per minute is 100 m³/min . And rate of change derived from the given question is 100 cubic meters.

Let us proceed and start by  denoting  the rate of alteration of volume of air in the balloon as r.

Given from the question one of the balloons loses 300 cubic meters of air every period of 3 min.

the rate of alteration of volume of air in balloon is -300/3 = -100 m³/min

After an interval of 10 minutes, the balloon has 500 m³ of air.

Let us consider x then

x = Vo + r x t  

where,

Vo = initial volume of air in the balloon

t =  time in minutes.

y = Vo+ r x t

500 = Vo + (-100) x 10

500 = Vo - 1000

Vo = 1500

Therefore, the initial volume of air in balloon was 1500 m³.

Given the balloons loses -100 m³/min.

The difference quotient for f(x) = x(¹/²) at x=37 and h=33 as ((70(¹/²)) - (37(¹/²))/33.

Compute the difference quotient?

The function f(x) = x(¹/²) at x=37 and h=33.

The difference quotient formula is: (f(x + h) - f(x))/h.

First, find f(x + h) by substituting x + h into the function: f(37 + 33) = ((37 + 33)(¹/²)).

Simplify f(x + h): f(70) = (70(¹/²)).

Find f(x) by substituting x into the function: f(37) = (37(¹/²)).

Plug f(x + h) and f(x) into the difference quotient formula: ((70^(1/2)) - (37(¹/²)))/33.

Now, you have computed the difference quotient for f(x) = x(¹/²) at x=37 and h=33 as ((70(¹/²)) - (37(¹/²))/33. m

To find the probability that one or more of the servers is operational, we need to find the probability that all three servers fail and subtract it from 1 (since we want the probability that at least one server is operational).

The probability that a server fails is 0.05, so the probability that a server is operational is 0.95. Since the failure of one server is independent of the other servers, the probability that all three servers fail is:
0.05 x 0.05 x 0.05 = 0.000125
Therefore, the probability that one or more servers is operational is:

1 - 0.000125 = 0.999875
Rounded to 6 decimal places, the probability is 0.999875. I'd be happy to help you with your question.
To find the probability that one or more servers are operational, we first need to find the probability that all servers fail, and then subtract that from 1. The probability that a single server fails is 0.05, and since the failure of each server is independent, we can multiply the probabilities together to find the probability that all servers fail.

Probability (all servers fail) = 0.05 * 0.05 * 0.05 = 0.000125
Now, subtract this from 1 to find the probability that one or more servers are operational:
Probability (one or more servers operational) = 1 - 0.000125 = 0.999875

So, the probability that one or more servers are operational is approximately 0.999875 or 99.9875%.

Steps (A) 2(x² + 6x + 9) = 3 + 18 and (B) 2(x² + 6x) = 3 can be used to solve the given quadratic equation.

An algebraic equation of the second degree in x is a quadratic equation.

The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.

So, let's examine the first option:

2(x² + 6x + 9) = 3 + 18

We'll now multiply 2 by each component of the other multiplier on the left:

2·x² + 2·6x + 2·9 = 3 + 18

2x² + 12x + 18 = 3 + 18

2x² + 12x - 3 = 18 - 18

2x² + 12x - 3 = 0

Let's examine the second option:

2(x² + 6x) = 3

We'll now multiply 2 by each component of the other multiplier on the left:

2·x² + 2·6x = 3

2x² + 12x = 3

2x² + 12x - 3 = 0

Therefore, steps (A) 2(x² + 6x + 9) = 3 + 18 and (B) 2(x² + 6x) = 3 can be used to solve the given quadratic equation.

In order to determine the short-run production function with the given information, we need to know the relationship between output, labor, and capital. In the short run, capital is fixed and equal to k = 2a.

Let's assume that the production function follows a Cobb-Douglas form:  Y = A * L^α * K^β
Where:
- Y is the output
- L is the labor input
- K is the capital input
- A is the total factor productivity
- α and β are the output elasticities of labor and capital, respectively
Since capital is fixed in the short run and K = 2a, we can rewrite the production function as: Y = A * L^α * (2a)^β
Now, this equation represents the short-run production function with fixed capital equal to 2a.

The carpenter needs to buy at least 8 4-foot lengths of wood to make all 60 dowels.

"Foot" is a unit of length commonly used in the imperial system of measurement, which is used primarily in the United States and some other countries. One foot is equivalent to 12 inches or 0.3048 meters. The foot is used to measure height, length, or distance in everyday situations, such as measuring the height of a person or the length of a room. In some contexts, the term "foot" may also refer to the base or lower part of a structure or object, such as the foot of a bed or the foot of a mountain.

In the given question,

To determine the least number of 4-foot lengths of wood the carpenter needs, we need to calculate how much wood is required to make all 60 dowels.

Since each dowel must be 6 inches long, we need a total of 60 x 6 = 360 inches of wood.

Each 4-foot length of wood is equal to 4 x 12 = 48 inches of wood.

Therefore, the carpenter needs 360/48 = 7.5 lengths of wood.

Since the carpenter cannot buy a fractional amount of a length of wood, they will need to buy at least 8 lengths of wood to make all 60 dowels.

Answer: The carpenter needs to buy at least 8 4-foot lengths of wood to make all 60 dowels.

The probability that at least one of the selected marbles is green when 4 marbles are selected at random and without replacement is 88.46%.

To find the probability that at least one of the selected marbles is green, we can use the complementary probability approach.
In this case, we'll calculate the probability that all the selected marbles are red and then subtract it from 1 to find the desired probability.

Step 1: Calculate the probability of selecting all red marbles.
There are 10 red marbles out of a total of 16 marbles. So the probability of selecting the first red marble is 10/16.

Step 2: Since we're selecting without replacement, there are now 9 red marbles and a total of 15 marbles left. The probability of selecting the second red marble is 9/15.

Step 3: For the third red marble, there are now 8 red marbles and a total of 14 marbles. The probability of selecting the third red marble is 8/14.

Step 4: For the fourth red marble, there are now 7 red marbles and a total of 13 marbles. The probability of selecting the fourth red marble is 7/13.

Step 5: Multiply the probabilities from Steps 1-4 to find the probability of selecting all red marbles: (10/16) x (9/15) x (8/14) x (7/13) = 5040/43680 = 0.1153

Step 6: Subtract the probability of selecting all red marbles from 1 to find the probability that at least one marble is green: 1 - 0.1153 = 0.8846

So the probability that at least one of the selected marbles is green when selecting 4 marbles at random and without replacement from a bag containing 10 red and 6 green marbles is approximately 0.8846 or 88.46%.

To determine the intervals where the function f(x) = ∫x^10(-t^2 + 2t - 3) dt is increasing, we need to follow these steps:

Step 1:To get the derivative of f(x).
Since f(x) is defined as an integral from 10 to x, we can use the Fundamental Theorem of Calculus. The derivative of f(x) is simply the integrand with x replacing t: f'(x) = -x^2 + 2x - 3
Step 2: To get  the critical points.
To find the critical points, we need to set f'(x) equal to 0 and solve for x: 0 = -x^2 + 2x - 3
Step 3: Solve the quadratic equation.
We can solve this quadratic equation using the quadratic formula, factoring, or other methods. In this case, factoring works: 0 = (x - 3)(-x + 1)
The critical points are x = 3 and x = 1.
Step 4: Test the intervals between the critical points.
Now, we will test the intervals between the critical points to see if f'(x) is positive or negative. This will determine if the function is increasing or decreasing.
Interval 1: x < 1
Choose any number in this interval, such as x = 0, and plug it into f'(x):
f'(0) = -(0)^2 + 2(0) - 3 = -3 (which is negative)
Interval 2: 1 < x < 3
Choose any number in this interval, such as x = 2, and plug it into f'(x):
f'(2) = -(2)^2 + 2(2) - 3 = -3 (which is negative)
Interval 3: x > 3
Choose any number in this interval, such as x = 4, and plug it into f'(x):
f'(4) = -(4)^2 + 2(4) - 3 = -7 (which is negative)
The function f(x) is not increasing in any interval.
