Question #N603
If $f(x) = 2x^2 + 3x - 1$, what is the value of $f(-2)$?
A. -9
B. -3
C. 3
D. 9
Correct Answer is: A
Substituting -2 for $x$ in the function $f(x) = 2x^2 + 3x - 1$, we get $f(-2) = 2(-2)^2 + 3(-2) - 1$. Simplifying, we have $f(-2) = 8 - 6 - 1 = 1$. Therefore, the value of $f(-2)$ is -9.
