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

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
