Find f(–2) for the function f(x) = 3x2 – 2x + 7.

Natasha_Volkova [10]

The correct answer is: 23

Explanation:

Given function:

$f(x) = 3x^2 - 2x + 7$ ---- (A)

f(-2) means that we have to put x = -2 in equation (A):

$f(-2) = 3(-2)^2 - 2(-2) + 7 \\ f(-2) = 3*4 + 4 + 7 \\ f(-2) = 12+4+7 \\ f(-2) = 23 \\$

Hence the correct answer is: f(-2) = 23.
