If f(x) = 3x^2 - x, find f(-2)

f(x) = 3x²

So,

f(-2) = 3(-2)²

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

=> f(-2) = 3 × 4

=> f(-2) = 12

Step-by-step it wont let me type the whole equation but f(−2)=14

okay, if you need all you need to do is ask, and i'll do my best to assist you.

step-by-step explanation:

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
