Section $2\mathrm{.}3-$ Calculating Limits Using the Limit Laws

The graphs of $f$ and $g$ are given. Use them to evaluate each limit$,$ if it exists. If the limit does not exist, explain.

$($a$)\underset{x2}{lim}[f(x)+g(x)]$

$($b$)\underset{x3}{lim}[\frac{f(x)}{g(x)}]$

$($c$)\underset{x2}{lim}[x^{2}f(x)]$
