Chapter 4: Rational Functions

If we add, subtract or multiply polynomial functions according to the function arithmetic rules defined in Section, we will produce another polynomial function. If, on the other hand, we divide two polynomial functions, the result may not be a polynomial. In this chapter we study rational functions - functions which are ratios of polynomials.
