Consider the function .

There is a vertical asymptote at:
NOTE: If there is more than one you can separate the values by a comma.

There a horizontal (or oblique) asymptote at
NOTE: This could be a function of x.

There is a y-intercept at .

If , , and are critical points, then can be broken up into the following unique intervals:
(), (), (), ().

For each of the intervals listed below, select the graph best representing the shape of the function in that interval.
