The equation that represents f(x) is f(x) = x²-2x-8.
What is the equation that represents f(x)?This equation is a parabola in the form of y = ax² + bx + c, where a, b, and c are constants.The value of a is 1, b is -2, and c is -8.The domain of this equation is all real numbers and the range is all real numbers greater than or equal to -8.The parabola of this equation is a "U" shape that opens upwards.The vertex is located at (x,y) = (1, -8) and the axis of symmetry is the line x = 1.The y-intercept is -8, which can be seen in the table of values.As x increases, the parabola will move up, and as x decreases, the parabola will move down.The graph of this equation is symmetrical around the y-axis.The equation that represents f(x) is d. f(x) = x²-2x-8. This is a quadratic function, which is a type of polynomial equation with one variable (in this case, x). A quadratic equation is defined as an equation of the form ax² + bx + c = 0, where a, b, and c are constants and a is not equal to 0.To find the equation that represents f(x), we can use the values given in the table and solve for the constants a, b, and c. For example, when x = 0, f(x) = -8, so we can set -8 = c. When x = 1, f(x) = -2, so we can set -2 = -a + b. Finally, when x = 2, f(x) = 6, so we can set 6 = 4a - 2b.We can then use these three equations to solve for the constants a, b, and c, and find that a = 1, b = -2, and c = -8. This gives us the equation f(x) = x² - 2x - 8, which represents the given table of values.To learn more about quadratic function refer to:

What percent of customers surveyed were 18-24? Round your answer to one decimal place
Answers
The percentage of customers who were surveyed and were 18 - 24, would be 24 %
How to find the percentage ?To find the percentage of customers who were surveyed and were between the ages of 18 and 24, find the total number of people surveyed :
= 25 + 30 + 35 + 25 + 10

Answers
The Largest interval in which the solution of the differential equation is defined is (-5, 3).
dy/dt + 2(t + 1)y² = 0 and y(0) = -1/15
Now, dy/dt + 2(t + 1)y² = 0
dy/dt = -2(t + 1)y²
By separating variables
dy/y² = -2(t + 1) dt
Integrating both sides
∫dy/y² = -∫(t + 1) dt
-1/y = -(t²+2t) + c
y(t) = /(t²+2t - c)
We know, y(0) = -1/15
So, -1/15 = 1/(0+0-c)
c = 15
∴ y(t) = 1/(t² + 2t - 15)
Now, y(t) is defined if t² + 2t - 15 ≠ 0
Let t² + 5t - 3t - 15 = 0
(t + 5)(t - 3) = 0
t = -5, 3
So, the intervals are (-∞ , -5), (-5, 3) and (3, ∞)
As t = 0 lies in between (-5, 3) hence the interval in which the solution is defined is (-5, 3)

Answers
The logarithm is expanded as much as possible to, log √(x^7y^-4) = (7/2) log (x) + (-2) log(y).
Simplifying the given logarithmic expression, log √(x^7y^-4).
Use the power rule of logarithms, log(a^x) = x log a.
Say, x= 1/2 and a = (x^7y^-4).
log √(x^7y^-4) = (1/2) log (x^7y^-4)
Now, use the multiplication property of the logarithms, log (ab) = log(a) + log(b). Consider a = x^7 and b = y^-4.
log √(x^7y^-4) = (1/2) log (x^7) + (1/2) log(y^-4)
Now, again use the power rule in both the terms,
log √(x^7y^-4) = (7/2) log (x) + (-4/2) log(y)
log √(x^7y^-4) = (7/2) log (x) + (-2) log(y)

7. A system of linear equations with fewer equations than unknowns is sometimes called an underdetermined system. Can such a system have a unique solution? Explain. Choices: a. No, it cannot have a unique solution. Because there are more variables than equations, there must be at least one free variable. If there is a free variable, the solution set contains a unique solution. b. No, it cannot have a unique solution. Because there are more variables than equations, there must be at least one free variable. If the linear system is consistent and there is at least one free variable, the solution set contains infinitely many solutions. If the linear system is inconsistent, there is no solution. c. Yes, it can have a unique solution. Because there are more equations than variables, there are no free variables. If the system is consistent and there are no free variables, the solution set contains a unique solution. If the system is inconsistent, there is no solution. d. Yes, it can have a unique solution. Because there are more variables than equations, there must be at least one free variable. If the linear system is consistent and there is at least one free variable, the solution set contains either a unique solution or infinitely many solutions. If the linear system is inconsistent, there is no solution.
Answers
The correct answer is b. No, it cannot have a unique solution. Because there are more variables than equations, there must be at least one free variable. If the linear system is consistent and there is at least one free variable, the solution set contains infinitely many solutions. If the linear system is inconsistent, there is no solution.
A linear system is a set of linear equations that can be expressed in the form Ax = b, where A is a matrix of coefficients, x is a vector of unknowns, and b is a vector of constants. Linear systems can be solved using a variety of methods, such as matrix inversion, Gaussian elimination, or the LU decomposition. In addition, linear systems can be used to model a variety of real-world problems, such as linear programming, optimization problems, and electrical networks.

Draw a rough sketch of the function (x-1)(x+2)(x+5)
Answers
Answer:
Step-by-step explanation:
Zeroes of a Function:The main idea you need to understand here is multiplicity, zeroes, and end behavior.
If a function has an odd degree that means that the end behaviors will be opposite so if on the right side the polynomial is going up, then on then on the left side it's going down and vice versa.
As for multiplicity, if the multiplicity or exponent of a zero is odd then it crosses the x-axis otherwise it has a turning point meaning it touches the x-axis and just turns around.
The last thing to understand is if the polynomial has a positive leading coefficient then the graph will be going up on the right side otherwise it will be going down.
We're given the function: f(x) = (x-1)(x+2)(x+5) and if you set each factor equal to zero, you can solve for the zeroes getting: x = 1, --2, and -5 as zeroes. Since the coefficients inside the factors are all positive when we multiply this out, we would get a positive leading coefficient and since the exponent of them is all one, the degree would be 3 when multiplying out the 3 binomials.
So on the right side it's going up, the left side it's going down (since odd degree) and at each zero it crosses the x-axis since they all have an odd multiplicity. This allows us to draw a rough sketch which I have provided using paint.,
Blake flips a fair coin and stops flipping once he gets a head. He gets the minimum of $16 and $2 n, where n is the total number of Blake's flips. For example, if Blake flips a head on the first try, then n=1. What is the fair value of this game?
Answers
If Blake flips a fair coin , and stops flipping once he get head , then the fair value of the game is 7 .
The Fair Value /Expected value is a mathematical definition that refers to the average outcome of a random process, such as a game or an investment. It is calculated by taking into account all the possible outcomes of the process, weighting each outcome by its probability of occurrence, and summing up the results.
We know that every coin flip has a equal chance of being heads or tails.
So, the probability of getting a head on each flip = 0.5 ;
The expected value is calculated as :
⇒ P(n=1)×(2¹) + P(n=2)×(2²) + P(n=3)×(2³) + P(n=4)×(2⁴) + P(n=5)×(2⁵) + P(n≥6)×(2⁶) ;
⇒ (0.5¹)×2 + (0.5²)×4 + (0.5³)×8 + (0.5⁴)×16 + (0.5⁵)×32 + (1-0.5-0.25-0.125-0.0625 - 0.03125)×64 ;
⇒ 5 + 0.03125 × 64 ;
⇒ 5 + 2
⇒ 7
Therefore , The Fair Value of this game is 7 .
