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. Here, the parabola opens down - ward and the highest point is at the intersection of the parabola and the y - axis.

Step2: Read coordinates

The x - coordinate of the vertex is 0 as it lies on the y - axis. The y - coordinate is 0 as it intersects the y - axis at 0.

Answer:

(0, 0)
