Use the function and graph to answer the questions about existence, limits$,$ and continuity.

$f(-2)\underset{x-2}{lim}f(x)\underset{x-2}{lim}f(x)f(-2)x=-2$

Find the limit of the function $a.$ as $x$ and $b.$ as $x-.$

$g(x)=\frac{6}{13+(\frac{1}{x})}$

a$.\underset{x}{lim}\frac{6}{13+(\frac{1}{x})}=,($Simplify your answer.$)$

b$.\underset{x-}{lim}\frac{6}{13+(\frac{1}{x})}=,($Simplify your answer.$)$
