About This Chapter
Exponential Functions - Chapter Summary
This chapter's lessons take a close look at exponential functions by examining their meaning and other related concepts that include decay, exponential growth and polynomial functions. Review these lessons any time from your computer or mobile devices to ensure you fully understand topics covered. Once you've completed this chapter, you will be ready to:
- Define an exponential function
- Differentiate between exponential growth and decay
- Discuss polynomial functions
- Identify transformations of exponential functions
Video lessons let you review quality materials in a visually engaging format that brings exponential functions to life. With each lesson is a printable transcript that features vocabulary words and a timeline that lets you skip to key topics without watching videos in full. Short quizzes and a chapter exam serve as assessment tools you can use to gauge your understanding of lesson concepts. Any questions you have about chapter topics can be sent to our experts.
1. What Is an Exponential Function?
Brand new technologies don't always catch on right away because they can be expensive and don't always work as well as they should. But once the price comes down, and they start to work better, it doesn't take very long before it seems like everyone has one. Learn about the numbers behind this, exponential functions!
2. Exponential Growth vs. Decay
How is it that it only takes four years for our computer to go from top-of-the-line to almost worthless? Well, it has something to do with what's called exponential decay, which we'll learn about here!
3. Polynomial Functions: Exponentials and Simplifying
How do we keep track of a rapidly multiplying population of bunnies? Well, those are simply powers of 2. Review powers and simplify problems with exponents in this lesson.
4. Transformation of Exponential Functions: Examples & Summary
All exponential functions follow a basic graph. But when you make changes to the function, you will see the graph shift and make changes. Watch this video lesson to learn how to easily identify these changes or transformations.
