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 lowest (or highest) point. In this graph, the parabola opens upwards and the lowest - point is where the curve changes direction.

Step2: Read coordinates

Looking at the grid, the x - coordinate of the vertex is 0 and the y - coordinate is - 10.

Answer:

(0, - 10)
