Here are the 2 things:

1 ) intercepts
2 ) asymptotes

Here are the 2 sentences:

1 ) These guys are functions.
2 ) Graphs hug asymptotes.

(Don't worry.  The next sections will tell you what these things mean.)

I'm guessing that you haven't seen my method before, so I'm going to go through all the gory details.  Since plotting points is for sissies, it will be our personal challenge to graph these things ONLY using the 2 things and the 2 sentences.  Oh, and one more little thing: our brain!

NOTE:  Until we learn Calculus, we'll really just be able to get pretty good rough sketches of these critters.  Calculus will fill in all the details!
