Chapter 2.R, Problem 60E

If $f$ and $g$ are the functions whose graphs are shown, let $P\left(x\right)=f\left(x\right)g\left(x\right)$, $P\left(x\right)=f\left(x\right)g\left(x\right)$, and $C\left(x\right)=f\left(g(x)\right)$.Find (a) $P\text{'}\left(2\right)$,(b) $Q\text{'}\left(2\right)$, and (c) $C\text{'}\left(2\right)$
