Question

Can someone help me figure this problem out?

Answer 1

f(-4) = 3

Explanation:

So when it says to find f(-4), all it's asking you to do is substitute -4 into the equation everytime you see an x.

So in this case it would be:

f(-4) =
`(-4)^(2)` +2(-4) - 5

= (16) - 8 - 5

= 3

so f(-4) = 3
