This section is an exploration of rational functions; specifically those functions that are made by taking a ratio (ie fraction) of polynomials.

By the end of this section students should be able to:
  • Identify a rational function in expressions and equations
  • Determine the implicit (aka natural) domain of a rational expression.
  • Solve equalities containing rational expressions.
  • Simplify and correctly notate (such as domain restrictions) rational expressions.
  • Identify very general endterm behavior of rational functions.
