Answer:
The vertex is the point (6,-31)
Step-by-step explanation:
we have
[tex]f(x)=x^2-12x+5[/tex]
This is a vertical parabola open upward
The vertex represent a minimum
Convert to vertex form
Complete the square
[tex]f(x)=(x^2-12x+6^2)+5-6^2[/tex]
[tex]f(x)=(x^2-12x+36)-31[/tex]
Rewrite as perfect squares
[tex]f(x)=(x-6)^2-31[/tex] -----> equation in vertex form
therefore
The vertex is the point (6,-31)
