Write a function k(x) that has the following transformations from the parent function f(x) = x.
Do not simplify equation.
Vertical reflection over the x axis, vertical stretch by a factor of 4.
~~~~~~~~~~~~~~~~~~~~~~ 

Step 1.  Vertical reflection over the x axis transforms the parent function f(x) = x
         to function g(x) = -x.


Step 2.  Vertical stretch by a factor of 4 transforms function g(x) = -x
         to function k(x) = -4x.


ANSWER.  k(x) = -4x.

Solved.
