Question

look at this graph: what are the coordinates of the vertex?

Explanation:

Step1: Identify vertex on graph

The vertex of a parabola is the highest or lowest point. In this graph, the parabola opens down - ward and the highest point is on the y - axis.

Step2: Determine x - coordinate

The x - value of the vertex on the y - axis is 0.

Step3: Determine y - coordinate

The y - value of the vertex where the graph reaches its maximum is 0.

Answer:

(0, 0)
