Image with description On a coordinate plane, a parabola opens up. It goes through (negative 6, 6), has a vertex of (0, negative 1), and goes through (6, 6).

Image with description On a coordinate plane, a parabola opens up. It goes through (negative 2.5, 6), has a vertex of (3, 0), and goes through (7.5, 4).

Explanation

The vertex is the turning point of a parabola. A vertex at 0 comma 0 means the vertex coordinates are (0, 0). Choice A describes a parabola with that vertex; the other choices give different vertex coordinates.
