Evaluate the function.
f(x) = 2x2
Find f(-3)

F(-3)=-12
because f(x) is y=2*2=4

Step-by-step explanation:

You have to understand two things about this question.

f(x) is a relative of y. So maybe it would help you if you wrote y = 2x^2The second thing you have to understand is when you see a number used instead of the x, that number goes into every x on the right.

f(-3) = 2(-3)^2

f(-3) = 2 * 9

f(-3) = 18

Remember that (-3) ^2 = -3 * - 3 = 9 a positive.
