To get a better idea of what the graph looks like, we should first plot a few additional points. Since the function is not defined at 0, it is a good idea to choose a few points close to zer, like x = 1/2, -1/2, 1/3, and -1/3.
| x | -3 | -2 | -1 | -1/2 | -1/3 | 0 | 1/3 | 1/2 | 1 | 2 | 3 | ||
| -10/3 | -5/2 | -2 | -5/2 | -10/3 | Undefined | 10/3 | 5/2 | 2 | 5/2 | 10/3 |
Plotting these additional points (and more if you are still not convinced -- try x = 1/10, 1/100, and so on) suggests the following graph.
