Chapter 1, Problem 28T

For $f\text{ and }g$ pictured, estimate the following.

$\begin{array}{l}\text{a}\text{. }\left(f+g\right)\left(3\right)\\ \text{b}\text{. }\left(f\cdot g\right)\left(0\right)\\ \text{c}\text{. }g\left(f\left(3\right)\right)\\ \text{d}\text{. }\left(f\circ g\right)\left(2\right)\\ \text{e}\text{. The interval}\left(\text{s}\right)\text{ over which }f\text{ is increasing}\text{.}\\ \text{f}\text{. The interval}\left(\text{s}\right)\text{ over which }g\text{ is decreasing}\text{.}\end{array}$
