Question 10 of 10

Given the polynomial function below, find F(-5).
F(x) = x2 - 2x-7
O A. -22
B. 42
O C. 8
D. 28

Answer 1

D. 28

Explanation:

We are given the following polynomial function:

`F(x) = x^2 - 2x - 7`

Find F(-5).

This is the value of F for which
`x = -5`. So

`F(-5) = (-5)^2 - 2(-5) - 7 = 25 + 10 - 7 = 28`

28, which means that the correct answer is given by option D.
