What are functions ?The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given that : f(x) =[tex]3x^{2} +5x -4[/tex]then ,= [tex]\frac{F(x + h)- F(x)}{h}[/tex]

How long will it take for the coffee to cool to 131" fork = 0.06889192 Round your answer to two decimal places.
Solution
We are given the equation
[tex]T=Ae^{-kt}+C[/tex]Room temperature, C = 73 degrees
Temperature at time t = 0, is T = 174 degrees
[tex]\begin{gathered} T=Ae^{-kt}+C \\ 174=Ae^0+73 \\ 174=A+73 \\ A=174-73 \\ A=101 \end{gathered}[/tex]Therefore, the equation becomes

What is the axis of symmetry, vertex, and y-intercept for f(x)=0.5x^2-2x-2
U
For the axis of symmetry, formula is,
[tex]x=\frac{-b}{2a}[/tex][tex]\begin{gathered} \text{where a=0.5 and b=-2} \\ x=\frac{-(-2)}{2(0.5)}=\frac{2}{1}=2 \end{gathered}[/tex]Hence, the axis of symmetry is 2.
To find the vertex, f(x)=0,
[tex]\begin{gathered} 0=0.5x^2-2x-2 \\ \text{Multiply both sides by 2} \\ 0=x^2-4x-4 \\ 0=(x^2-4x)-4 \\ 0=(x-2)^2-(4-2_{} \\ 0=(x-2)^2-2 \\ \text{Vertex are (2, -2)} \end{gathered}[/tex]Hence, the vertex are (2, -2).

in how many ways can 9 people stand in a line
Suppose a basketball player has made 273 out of 385 free throws. If the player makes the next 3 free throws, I will pay you $27. Otherwise you pay me $16. Step 2 of 2 : If you played this game 891 times how much would you expect to win or lose?
By probability, If you played 891 times, you expect to lose $16.
Total Possible Throws = 385
Number of throws = 273
Let P(T) be the Probability that the player makes the next throw
P(T) = 273 / 385
The probability that the player makes the next three throws is then given by:
= P(T) × P(T) × P(T)
= 273 / 385 × 273 / 385 × 273 / 385
= (273 / 385)²
= 0.35653794139
= 0.357
Let P(T') be the probability the player doesn't make the next two throws
P(T') = 1 - P(T)
P(T') = 1 - 0.357
P(T') = 0.643
The expected gain for the player turns is given by:
(Probability of making both throws) * $27 + (Probability of NOT making both throws) x ( - $16 )
= 0.357 × $27 - 0.643 × $16
= $9.639 - $10.288
= - $0.649
b.
The probability that he makes the next 891 throws.
= P(T)⁸⁹¹
= (273/385)⁸⁹¹
Let P(T') be the probability the player doesn't make the next three throws
P( T' ) = 1 - P( T )
P( T' ) = 1 - 19.449493e-134
P( T' ) = 1
The expected gain or loss for the player turns is given by:
(Probability of making all 626 throws) * $5 + (Probability of NOT making all 626 throws) x (-$10)
= (273/385)⁸⁹¹ × 27 + 1 × - 16

A rented office space has a monthly income of $3,800. A suitable gross income multiplier derived from market data is 11.1. What would the estimated value be? Round to the nearest $1,000.
The estimated value after round will be $506,000.
What is Rounding number?
To making a number simpler but keeping its value close to what it was, is called Rounding.
Given that;
Monthly income of a rented office = $3,800
A suitable gross income multiplier derived from market data = 11.1.
Now,
We know that;
Gross income multiplier = Sale price ÷ Gross income
Here, Gross income multiplier = 11.1
And, The annual gross income will be,
= Monthly gross income x Number of month in a year
= $3,800 x 12
= $45,600
Thus, Estimated sale price is calculated as;
11.1 = Estimated Sale price ÷ $45,600
Estimated Sale price = 45,600 x 11.1
= $506,160
After round off we get;
Estimated Sale price = $506,000
Thus, The estimated value after round will be $506,000.

The relationship between the two is given as;
[tex]f(x)\text{ = -6x-3}[/tex]a) Here, we have an input, and we want to get the output
To solve this, we just need to substitute the value of -8 for x in the relation
