Question

If f(x)= - 4x-4, g(x)= 4x² + 4x + 2, and h(x)= 3x2 – 3, find f(3).
f(3) =
(Simplify your answer.)

Answer 1

Answer:

$f(3) = -16$

Step-by-step explanation:

Given

$f(x)= - 4x-4$

$g(x)= 4x^2 + 4x + 2$

$h(x)= 3x^2 - 3$

Required

$f(3)$

We have:

$f(x)= - 4x-4$

Substitute $x = 3$

$f(3) = -4 * 3 - 4$

$f(3) = -12 - 4$

$f(3) = -16$

Hence:

$f(3) = -16$
