What is the vertex of the parabola?

vertex =(1,-4)

Step-by-step explanation:

Given is a graph of a parabola

We have to find its vertex

From the graph we observe that the parabola is symmetric about a vertical line x=1.

The graph decreases upto x=-1 and then starts increasing from x=-1

x intercepts are -1 and 3

y intercept is -3

Minimum point = (1,-4)

Since the parabola is open up, the minimum is reached at the vertex.

Hence vertex =(1,-4)

1. 34

2. 268

3. x=14.4
