Question

If you vertically stretch the absolute value parent function, f(x) = [xl, by a

factor of 5, which of these is the equation of the new function?

Answer 1

`g(x) = 5|x|`

Explanation:

Given

`f(x) = |x|`

`b =5` --- vertically stretch

Required

The new function

The rule for vertical stretch is:

`g(x) = bf(x)`

So, we have:

`g(x) = 5 * |x|`

`g(x) = 5|x|`
