About This Chapter
Operations with Functions - Chapter Summary
This chapter offers a well-rounded analysis of operations with functions. Experienced instructors have created entertaining lessons that examine standard and polynomial functions and detail how to identify and perform basic operations on functions. The lessons are accessible as videos that average 8 minutes each or full transcripts you can print or read online. Study them using your format of choice, and check your knowledge of their contents by taking short quizzes and a chapter exam. Once you've completed this chapter, you will be ready to:
- Discuss the identification and notation of functions
- Add, subtract, multiply and divide functions
- List and define the terminology of polynomial functions
- Evaluate a polynomial in function notation
1. Functions: Identification, Notation & Practice Problems
A function is simply a rule that takes one number and turns it into another. But some special conditions must apply for it to be a true mathematical function. Learn about those conditions and how we write functions here!
2. How to Add, Subtract, Multiply and Divide Functions
Adding, subtracting, multiplying and dividing functions is about as simple as substituting in expressions and then just doing whichever operation it asks you to do. Check out this video lesson to see some examples of this and learn just how easy it is!
3. Terminology of Polynomial Functions
After watching this video lesson, you will be able to understand and use the words associated with polynomial functions like a pro. You will see words, such as leading coefficient, and you will immediately know what it is referring to.
4. How to Evaluate a Polynomial in Function Notation
This lesson will review how to evaluate polynomials in function notation. Along with an analogy to explain the process, examples will be given and worked during the lesson.
