Question

if f(x) = -4x - 3, g(x) = 5x² - 5x + 5, and h(x) = -6x² - 2, find f(-3).
f(-3) = \square
(simplify your answer.)

Explanation:

Step1: Substitute $x=-3$ into $f(x)$

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

Step2: Calculate the product first

$-4(-3) = 12$

Step3: Subtract 3 from the result

$12 - 3 = 9$

Answer:

$9$
