Polynomial Function Basics in Precalculus - Chapter Summary and Learning Objectives

Learning precalculus is a process that requires a lot of time and dedication. Sometimes, it helps to get assistance outside of your classroom to boost your comprehension and reinforce concepts. In this chapter are lessons designed to help you better understand polynomial function basics in precalculus. Take time to learn the terminology, definitions and mathematical operations associated with this subject area. Top instructors explore function notation, polynomial graphs and the behavior of polynomials. Also, closely examine Pascal's triangle and the binomial theorem.

To make your journey through this chapter simple, review the lessons as fun videos or full transcripts. Timelines are available that allow you to identify and skip to key topics within the videos without watching them in full. Review lessons in any sequence and as often as you'd like. At any time, feel free to test your knowledge of the subject matter by taking quizzes and a chapter exam. In no time, you will have a better grasp of:

  • Terminology associated with polynomial functions and how to evaluate a polynomial in function notation
  • Properties, factoring, exponential and simplifying polynomial functions
  • How to understand basic polynomial graphs and find intervals of polynomial functions
  • Short-run and long-run behavior of polynomials and how to graph cubics, quartics, quintics and beyond
