In this lesson, you will learn to identify the inputs and outputs as the domain and range of a function. You will calculate real-world examples using money, area, and perimeter to understand how the use of the domain and range of a function can be applied in everyday life.
When you finish this lesson, you will be able to:
- Describe the “domain” and “range” of a function.
- Determine a reasonable domain and range for the function when given a description of a function in a situation.
Here are the activities that will help you reach those goals:
- 4.12.1: Determining Reasonable Inputs and Outputs
- 4.12.2: Domain: The Input of a Function
- 4.12.2: Self Check
- 4.12.2: Additional Resources
- 4.12.3: Range: The Output of a Function
- 4.12.3: Self Check
- 4.12.3: Additional Resources
- 4.12.4: Using Graphs to Determine the Domain of a Function
- 4.12.5: Using Functions to Answer Real-World Questions
After that, you’ll practice and review.
