Answer:
1
Step-by-step explanation:
The value of the output given by the inverse for a given input is the same as the input of the original function that results in the output equal to the given input.
So, 2x + 2 = 4, meaning the answer is 1
Answer:
C
The problem:
What can x not be so that the following is a function:
(8,5), (6, 8), (X, 11), (0, 12)?
Step-by-step explanation:
A set of points is a function if every element,x, in the domain is paired with one y from the range.
So basically we don't want any repeated x. x would be a repeat if x is 8 since it has already been paired with 5.
Summary we are saying x can't be 8 because x=8 is already paired with y=5 so we can't pair it with another different y.

Answer:
y = - 15.57x² + 179.32x + 0.20
510
Step-by-step explanation:
The quadratic model obtained using a quadratic regression solver with Coefficient rounded to the nearest hundredth is :
y = - 15.57x² + 179.32x + 0.20
Where, height = y
x = time
Using the model obtained ; the height, to the nearest foot, at a time, x = 6.4 seconds.
y = - 15.57x² + 179.32x + 0.20
y = - 15.57(6.4^2) + 179.32(6.4) + 0.20
y = 510.1008
y = 510
