What is a Rational Function?
A rational function is of the form
\(f(x) = \frac{{p(x)}}{{q(x)}}\)
where p(x) and q(x) ar polynomials and q(x) ≠ 0.

How to graph rational functions?
Graphs of the form
\(y = \frac{{ax + b}}{{cx + d}}\)
1. graphs into hyperbolas
2. vertical asymptote occurs at the x value that makes the denominator = 0.
3. horizontal asymptote occurs at the line y = a/c.
