MTH 219 Week 5 Introductory & Intermediate Algebra for College Students, Ch. 8, Sections 8.3-8.4: Basic Functions

Congrats on getting to the final reading of the course! In Ch. 8 you finish learning about functions for this course. This chapter focuses on Composite and Inverse Functions. This reading will help you gain a larger math vocabulary. If you do not understand a term, look it up on the internet. There may be a definition on the internet that resonates with you more than the definitions in this reading. Keep up all the hard work! You are close to the finish line.

• View one of the following Week 5 videos:

  • Patrick Just Math Tutorials: “Composition of Functions“
  • Khan Academy’s “Evaluating Composite Functions: Using Graphs“

Write an equation to represent f(x) and g(x). Describe a method you can use to evaluate f(g(2)). Would the answer be the same as g(f(2))? Why or why not?
