B. f(x) = 0
C. x = 2
D. f(x) = 4

2. 8-4 Graphing Rational Functions
Graph rational functions with horizontal and vertical asymptotes.
Graph rational functions with oblique asymptotes and point discontinuity.

3. 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.
