Question

Function g can be thought of as a scaled version of f(x) = |x|. What is the equation for g(x)?

Answer 1

Function g can be thought of as a scaled version of f(x) = |x|.

What is the equation for g(x)?

Answer 2

`f(x)=|x|`

`g=k|x|` where
`k` is the scale factor.

We notice that
`g(-3)=4`.

Therefore

`k|-3|=4\\3k=4\\k=(4)/(3)`

So

`g=(4)/(3)|x|`
