Question

Identify the vertex of the parabola.

A.(1, 7)
B.(−1, 3)
C.(−2, 4)
D.(0, 4)

Answer 1

Explanation:

The vertex is always at the highest point of the parabola or the lowest point, depending upon which way it opens. Ours opens upwards, so the vertex is a min (aka, it's at the lowest point). That lowest point is located at (-1, 3), choice B.
