Question

F(x) = –x2 – 4 for x = –3
–9

1

–13

–1

Answer 1

x = -3

Plug in -3 for x

I'm guessing you meant -(x^2) - 4

x = -3

f(-3) = -((-3)^2) - 4

First square - 3

-3^2 = -3 x - 3 = 9

f(-3) = -(9) - 4

Simplify.

f(-3) = - 9 - 4

Combine like terms.

f(-3) = - 13

f(-3) = -13 is your answer

hope this helps
