Answer
The graph is continuous at all values except for $x=\pi$.
Work Step by Step
Graph the three functions according to their domain restrictions. (see below)
You can see that the graph is continuous at all points except where $x=\pi$. Thus, the limit exists for all values except for $x=\pi$, since the limit of the function as it approaches $\pi$ from the left is different from the limit of the function as it approaches $\pi$ from the right.
