Lesson Plan: Domain of Rational Functions Mathematics • Third Year of Preparatory School

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify the domain of a rational function and the common domain of two or more rational functions.

Objectives

Students will be able to

  • identify the domain of a rational function in which the denominator is a linear, a quadratic, a cubic, or a higher-degree polynomial,
  • find the common domain of two or more rational functions,
  • find unknowns in a function given the domain.

Prerequisites

Students should already be familiar with

  • finding zeroes of polynomial functions,
  • set notation,
  • factoring quadratic and cubic functions.

Exclusions

Students will not cover

  • writing a rational function as partial fractions,
  • finding the range of rational functions,
  • finding the domain of the sum, difference, multiplication, and division of two rational functions.
