Now we're ready to graph... Remember that plotting points is for sissies, so use your brain!
First, let's graph our intercepts and asymptotes on the graph:
* Remember that the graph CANNOT cross the y-axis anywhere else and it CANNOT cross the x-axis at all!
Now, we use our brains and our sentences...
