Question

Complete the square to rewrite y=x2 - 6x + 2 in vertex form. Then state whether the vertex is a maximum or a minimum and give its coordinates.

A. Maximum at (-3, -7)

B. Maximum at (3,-7)

C. Minimum at (3, -7)

D. Minimum at (-3, -7) ​

Answer 1

C) Minimum at (3,-7)

Explanation:

`y=x^2-6x+2`

`0=x^2-6x+2`

`0+7=x^2-6x+2+7`

`7=x^2-6x+9`

`7=(x-3)^2`

`0=(x-3)^2-7`

`y=(x-3)^2-7`

Because the parabola opens upward, the vertex is the minimum of the function. Therefore, the vertex is the minimum at (3,-7).
