Question

Determine the vertex of the parabola whose graph is given below

Answer 1

For a parabola that opens upward, the vertex is the lower point that belongs to the parabola.

For a parabola that opens downward, the vertex is the highest point that belongs to the parabola.

Since the parabola shown in the graph opens downward, the vertex is the highest point, and its coordinates are (-5, 5).
