1. ## Holes and Graphs

We are doing some graphing in our algebra class and the instructor asked the following question:

When do holes occur in a rational function?

I've flipped through my textbook, but can't find anything about holes.

Can anyone help? (This is an extra credit question for the class).

Thanks!

since this is extra credit, we cannot do the problem for you. but this should help. number 4 under "Steps for graphing rational functions..." is of particular interest to you, but you should familiarize yourself with the others as well

a note for horizontal asymptotes: be aware that you can have two, you might get a different constant value for each limit
