Question

The vertex of this parabola is at (-3,2). which of the following could be its equation?

Answer 1

B

Explanation:

Notice that the vertex is 2 units above the x-axis. The equation of this parabola must end in +2 to reflect this fact. Thus, we narrow down our answer choices to B and C.

(x + 3) in choice B is correct, since the vertex is to the left of the y-axis.
