Question

What is the vertex of the following function? Is this minimum or maximum value?

Answer 1

maximum value at (5, 9 )

Explanation:

The vertex is the point on the graph where it goes from an increasing function to a decreasing function as x increases from left to right.

vertex = (5, 9 )

Since the function increases to the vertex then turns at the vertex and decreases.

It reaches a maximum value at the vertex of y = 9
