what are the coordinates of the vertex of the function f(x) = x2 - 12x + 5?
(6, 31)
(-6, 31)
(6.-31)
(-6, -31)

The vertex is the point (6,-31)

Step-by-step explanation:

we have

This is the equation of a vertical parabola open upward

The vertex is a minimum

Convert the quadratic equation in vertex form

where

a is a coefficient

(h,k) is the vertex

Complete the squares

Rewrite as perfect squares

therefore

The vertex is the point (6,-31)
