Question

using the graph, determine the coordinates of the vertex of the parabola.

Explanation:

Step1: Locate the vertex on graph

The vertex of a parabola is the highest or lowest point. In this graph, it is the highest point.

Step2: Read x - coordinate

Looking at the x - axis, the x - value of the vertex is 1.

Step3: Read y - coordinate

Looking at the y - axis, the y - value of the vertex is 4.

Answer:

(1, 4)
