Question

Given the polynomial function below, find Æ-5).
F(x) = x - 22-7

Answer 1

f(-5)= 28

Explanation:

Answer 2

f(-5)= 28

Explanation:

The function is:

f(x)= x^2-2x-7

To find the answer put the value of -5 for all x's.

f(x)= x^2-2x-7

f(-5)=(-5)^2 - 2(-5)-7

f(-5)=25+10-7

f(-5)=35-7

f(-5)= 28 ...
