Question #N346
If the function $f(x) = x^2 - 3x + 2$ is graphed in the $xy$-plane, what is the $y$-intercept of the graph?
A. -2
B. 2
C. -1
D. 1
Correct Answer is: B
The y-intercept of a graph occurs when $x = 0$. So, to find the y-intercept, we substitute 0 for $x$ in the function: $f(0) = 0^2 - 3(0) + 2 = 2$. Therefore, the y-intercept of the graph is (0, 2).
