"Title" Tutorial Summary : 
This tutorial describes the concept of rational functions. These are a type of polynomial functions whose vertical and horizontal asymptotes helped describe the domain of rational functions. It is important to determine the degrees of the two functions that are part of a rational function so asymptotes could be determined.
This tutorial describes operations on rational functions through the use of examples. Simplification of rational functions is achieved by factoring the numerator function of rational functions and the denominator function of rational functions. Solving polynomial equations involves comparing the degrees and evaluating both functions so simplification can be achieved as much as possible.

Tutorial Features: 
Specific Tutorial Features:
