Question #N261
The function $f(x) = ax^2 + bx + c$ has a vertex at $(-2, 3)$ and passes through the point $(0, 1)$. What is the value of $c$?
A. -5
B. 1
C. 3
D. 5
Correct Answer is: B
Since the parabola passes through the point (0, 1), we know that f(0) = 1. Substituting x = 0 into the equation f(x) = ax^2 + bx + c, we get f(0) = a(0)^2 + b(0) + c = c. Therefore, c = 1.
