8-4 Graphing Rational Functions Graph rational functions with horizontal and vertical asymptotes. Graph rational functions with oblique asymptotes and point discontinuity.

Cool features: They have asymptotes! They can have excluded values in both domain and range! Sometimes they just have a hole in them! To graph: Figure out asymptotes. Find some other points.

If functions have common factors in top and bottom, you get HOLES!
