Use a Graph to Determine Whether the Function Is Continuous $$h ( x ) = \left\{ \begin{array} { l l } \frac { | x | } { x } & \text { if } x \neq 0 \\0 & \text { if } x = 0\end{array} \right.$$

Short Answer

Use a graph to determine whether the function is continuous on its domain. If it is not continuous on its domain, list the points of discontinuity.
​ $$h ( x ) = \left\{ \begin{array} { l l } \frac { | x | } { x } & \text { if } x \neq 0 \\0 & \text { if } x = 0\end{array} \right.$$
