Question

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

Explanation:

Step1: Identify vertex on graph

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

Step2: Read x - coordinate

The x - value of the vertex of a parabola symmetric about the y - axis is 0.

Step3: Read y - coordinate

By looking at the graph, the y - value of the vertex is - 2.

Answer:

(0, - 2)
