Question

the parent function of the function g(x)=(x-h)^2+k is f(x)=x^2. the vertex of the function g(x) is located at (9,8). what are the values of h and k?

Answer 1

The answer is g(x) = (x - 9)^2 + -8

So 9 and -8 are the correct answers

Explanation:

The guy above got the first one right but not the second one, it's supposed to be negative.

Answer 2

h = 9, k = 8

Explanation:

`\text{The vertex form of an an equation of a quadratic function:}\\\\y=a(x-h)^2+k\\\\(h,\ k)-vertex\\\\\text{We have}\ g(x)=(x-h)^2+k,\ \text{and the vertex in}\ (9,\ 8).\\\\\text{Therefore}\ h=9\ \text{and}\ k=8.\ \text{substitute:}\\\\g(x)=(x-9)^2+8`
