C. y = x² – 6x + 10

Step-by-step explanation:

Formula f(x)=a(x-h)^2+k (h,k) is vertex

Y=a (x-3)^2+1

Plug in y intercept

10=a (0-3)2+1

10=-3^2a+1

10=9a+1

9=9a

A=1

Y=(x-3)2 +1

Y=x2-6x+9+1

Y=x2-6x+10

C. y = x² – 6x + 10

Step-by-step explanation:

Formula f(x)=a(x-h)²+k (h,k) is vertex

Y=a (x-3)²+1

Plug in y intercept

10=a (0-3)²+1

10=-3²ᵃ+1

10=9a+1

9=9a

a=1

Y=(x-3)² +1

Y=x²-6x+9+1

Y=x²-6x+10
