Which is not an asymptote of the function Warm up Which is not an asymptote of the function A. x = –6 B. f(x) = 0 C. x = 2 D. f(x) = 4
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!
