Question 1: 11 pts
Find the vertex of the parabola y = x2 - 10x + 16.
A. (-5,91)
B. (-9,5)
C. (5,-9)
D. (8,0) and (2,0)

Answer 1

`\\ \rm\rightarrowtail y=x^2-10x+16`

`\\ \rm\rightarrowtail y=x^2-10x+16+9-9`

`\\ \rm\rightarrowtail y=x^2-10x+25-9`

`\\ \rm\rightarrowtail y=(x-5)^2-9`

Vertex form

• y=a(x-h)^2+k

So

vertex:-

• (h,k)=(5,-9)
