Rational Functions -  Horizontal and Oblique Asymptotes

This video looks at the end behaviors of rational functions. With polynomial functions, we had four different end behaviors:

Positive, even function (both ends pointing up);
Negative, even function (both ends pointing down);
Positive, odd function (bottom-left to top-right);
Negative, odd function (top-left to bottom-right). 

Rational functions have two additional types of end behavior:

Horizontal line (both ends eventually go to a single value) or
Oblique line (both ends eventually look like a polynomial).
