Let

Find each point of discontinuity of $f$, and for each point of discontinuity, evaluate the indicated one-sided limits.

NOTE: When using interval notation in WeBWorK, remember that:
You use 'INF' for $\infty$ and '-INF' for $-\infty$.
If you have more than one point, give them in numerical order, from smallest to largest.
If you have extra boxes, fill each in with an 'x'.

Point 1: $C =$
$\displaystyle{\lim_{x \rightarrow C^{-}} f(x)}$ =
$\displaystyle{\lim_{x \rightarrow C^{+}} f(x)}$ =

Point 2: $C =$
$\displaystyle{\lim_{x \rightarrow C^{-}} f(x)}$ =
$\displaystyle{\lim_{x \rightarrow C^{+}} f(x)}$ =

Point 3: $C =$
$\displaystyle{\lim_{x \rightarrow C^{-}} f(x)}$ =
$\displaystyle{\lim_{x \rightarrow C^{+}} f(x)}$ =
