About This Chapter
Composing Functions - Chapter Summary
Take time to review this chapter if you want to strengthen your ability to compose functions. Lessons delve into this math concept by providing definitions and clear examples of composite and inverse functions, common algebraic expressions, linear relationships and more. View the lessons when your schedule permits. In no time, you will be prepared to:
- Compose functions, and evaluate functions that have been composed
- Convert domain and range values into ordered pairs, then construct a graph
- Evaluate composite functions
- Write, find and predict the existence of inverse functions
- Identify the most common equations in algebra
Watch the fun video lessons from your computer, smartphone or tablet to strengthen your knowledge of the process of composing functions wherever you can access the Internet. Read full transcripts of the lessons if you prefer to review the lessons in print. Assess your understanding of functions by taking short multiple-choice quizzes. If you answer any questions incorrectly, simply click the link next to the answer to revisit the related portion of the video lesson.
1. How to Compose Functions
Function composition is the process of putting two or more functions together. This video lesson will explain how this process works and also show you how to evaluate functions that have been composed.
2. Model a Linear Relationship Between Two Quantities
In this lesson, we will learn about modeling linear relationships by converting domain and range values into ordered pairs and then constructing a graph.
3. How to Evaluate Composite Functions
Sometimes a math function depends on the outcome of another function. This lesson breaks down this chain reaction, called a composite function, and how to evaluate them.
4. Inverse Functions
Inverse functions are two functions that do exactly opposite things. Check out this lesson to learn about how to write inverse functions, find inverse functions, and predict whether or not they exist.
5. Common Algebraic Equations: Linear, Quadratic, Polynomial, and More
Watch this video lesson to see the kinds of equations that you will come across most often in algebra. Learn to distinguish them by just looking for the identifying components of each equation.
