3-28.

Find slope functions, , for the following functions:

Use the Power Rule. If

, then

(Careful!)Remember that π is just a number, not a variable!

Since

, what is the slope function of? Use that to find the slope function of.

*f*(*x*) = 2(*x*− 2)^{4}+ 18*x*is a horizontal shift of, whose slope function is easy to find with the Power Rule (see hint in part (a)). As for, THINK! Since slopes will shift with the function...will equal a shifted version of'.

See hint in part (a).
