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 the given graph, the parabola opens upwards and the lowest - 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 parabola touches the y - axis is 2.

Answer:

(0, 2)
