• 4.1: Rational Functions
In this section, we explore functions based on power functions with negative integer powers, called rational functions.
• 4.2: Further Topics in Functions
This section serves as a watershed for functions which are combinations of polynomial, and more generally, rational functions, with the operations of radicals. It is business of Calculus to discuss these functions in all the detail they demand so our aim in this section is to help shore up the requisite skills needed so that the reader can answer Calculus’s call when the time comes. We briefly recall the definition and some of the basic properties of radicals from Intermediate Algebra.
