Sketch a graph $of$ a function, $f,$ must have the following properties.

Draw $in$ vertical asymptote$(s)if$ needed.

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

$\underset{x-4}{lim}f(x)=-2,$ but $f(-4)$ undefined

$\underset{x-1^{-}}{lim}f(x)=2,\underset{x-1^{+}}{lim}f(x)=-4,$ and $f(-1)=2$

$\underset{x{3}^{-}}{lim}f(x)=$ and $\underset{x{3}^{+}}{lim}f(x)=-$

$f(x)=0$ when $x=4$

$f(6)=2$ and $f^{\text{'}}(6)=0$

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