Question

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

Explanation:

Step1: Identify the vertex

The vertex of a parabola is the highest (or lowest) point. Looking at the graph, the parabola opens downward, so the vertex is the maximum point.

Step2: Determine the coordinates

The vertex is on the y - axis (since it's symmetric about the y - axis here). The x - coordinate of the vertex is 0. To find the y - coordinate, we look at the vertical position of the vertex. From the graph, the vertex is at y = 8 (by estimating the grid lines, each grid seems to be 1 unit, and the vertex is 8 units up from the origin on the y - axis).

Answer:

(0, 8)
