For the function = − + + , what are the coordinates of the vertex? Is it a maximum or minimum point? Show all work algebraically to earn full credit.

Vertex: (1,3)

Maximum

Step-by-step explanation:

Given the quadratic function .

First, find the coordinaes of the vertex:

Hence, the vertex is at point (1,3).

The leading coefficient is -2, this means parabola opens downwards and the value of the function at vertex is the maximum value of the function.
