In this lesson, you will use graphs to learn about the domain of functions. You will examine and interpret different types of graphs that represent real-world situations to determine the domain and range.

When you finish this lesson, you will be able to:

• 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:

• 4.13.1: Different Features of a Graph
• 4.13.2: Graphs of Functions
  • 4.13.2: Self Check
  • 4.13.2: Additional Resources
• 4.13.3: Finding Domain and Range Using a Graph
  • 4.13.3: Self Check
  • 4.13.3: Additional Resources
• 4.13.4: Real-World Domain and Range
  • 4.13.4: Self Check
  • 4.13.4: Additional Resources
• 4.13.5: Graph of a Function and the Domain and Range Connection

After that, you’ll practice and review.
