Answer:

D. 23​

Explanation:

To find f(-2) for the function f(x) = 3x^2 - 2x + 7, we need to substitute x = -2 into the function and calculate the value.

Let's substitute x = -2 into the function:

f(-2) = 3(-2)^2 - 2(-2) + 7

Now, let's simplify the expression:

f(-2) = 3(4) + 4 + 7

= 12 + 4 + 7

= 16 + 7

= 23

Therefore, f(-2) = 23.
