Given f(x) = 4x^3 − 12x^2 + 40x + 12, find f(–2).

-148

Step-by-step explanation:

f(x) = 4x³ − 12x² + 40x + 12

This is the equation you have.  You have to find f(-2).  To find it, you have to plug in -2 wherever there is an x.

f(-2) = 4(-2)³ - 12(-2)² + 40(-2) + 12

f(-2) = 4(-8) - 12(4) + 40(-2) + 12

f(-2) = -32 - 48 - 80 + 12

f(-2) = -148

okay wait before i answer, is this for your points on a graph?

f(x) = y

f(-3) = -5
