Question #N688
The function $f(x)$ is defined by $f(x) = 3x^2 - 2x + 1$. What is the value of $f(-2)$?
A. -11
B. -7
C. 11
D. 19
Correct Answer is: D
Substituting -2 for x in the given equation yields $f(-2) = 3(-2)^2 - 2(-2) + 1$. This simplifies to $f(-2) = 3(4) + 4 + 1$, or $f(-2) = 12 + 4 + 1$, or $f(-2) = 19$.
