4.9.0 • Lesson Overview

In this lesson, you will apply your understanding of average rate of change to interpret or create graphs of functions that are less well defined and that model real-life situations that are more complex.

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

  • Explain the average rate of change of a function in terms of a situation.
  • Describe important features of a graph and explain what they mean in a situation.
  • Sketch a graph that shows important features of the situation, given a description or a visual representation of a situation.

Here are the activities that will help you reach those goals:

  • 4.9.1: Analyzing and Comparing the Properties of Graphs
  • 4.9.2: Interpreting Graphs Without Units
    • 4.9.2: Self Check
    • 4.9.2: Additional Resources
  • 4.9.3: Sketching Graphs of Functions
    • 4.9.3: Self Check
    • 4.9.3: Additional Resources
  • 4.9.4: Using Verbal Descriptions to Create Graphs of Functions
  • 4.9.5: Representing Quantities in a Situation

After that, you’ll practice and review.

  • 4.9.6: Practice
  • 4.9.7: Lesson Summary
