Based on the known points plotted on the graph, determine what intervals the graph should be broken into.  
Plotted points are: $\left(-3,0\right),$$\left(0,1\right),\left(2,0\right),$ & $\left(5,0\right)$

$-\infty\rightarrow-3,-3\rightarrow0,0\rightarrow5,5\rightarrow\infty$

$-\infty\rightarrow-3,-3\rightarrow0,0\rightarrow2,2\rightarrow5,5\rightarrow\infty$

$-\infty\rightarrow-3,-3\rightarrow0,0\rightarrow2,2\rightarrow\infty$

$-\infty\rightarrow0,0\rightarrow2,2\rightarrow5,5\rightarrow\infty$
