Question

what are the coordinates of the vertex of the parabola shown? A) (90,50)B) (10, 50)C) (10, 700)D) (50,700)

Answer 1

In a parabola, the vertex is located at the maximum or minimum point of the curve.

Since the given parabola opens downwards, it has a maximum point.

Looking at the graph, the x-coordinate of the maximum point is 50 and the y-coordinate of the maximum point is 700.

Therefore the vertex is located at (50, 700).

Correct option: D.
