Question

the transformation form (vertex form) of the absolute value function is y=a×[x-h] +k. what is the value of a, h and k in the parent function y=[x]

Answer 1

We have the parent function y=x^2 and we have to express it in vertex form.

We can rearrange it like:

`\begin{gathered} y=x^2 \\ y=x^2+0 \\ y=(x-0)^2+0 \end{gathered}`

This is the result as the vertex of the parent function is at (h,k)=(0,0).

The quadratic coefficient is 1.

Answer: a=1, h=0, k=0
