Question 1141287: f(x) = −x^2 + 8x − 16
Rewrite the function in
f(x) = a(x − h)2 + k
form. Found 2 solutions by Boreal, josgarithmetic:Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! vertex is x=-b/2a or -8/-2 = 4
f(4)=0
so have (x-4)^2+0 without a defined.
this is x^2-8x+16
multiply by -1 and have -x^2+8x-16
so f(x)= -(x-4)^2 in vertex form.
