In this lesson, you will determine whether situations are characterized by exponential growth or by exponential decay given real-world scenarios of descriptions and graphs.

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

• Use graphs to compare and contrast situations that involve exponential decay.
• Use information from a graph to write an equation that represents exponential decay.

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

• 5.7.1: Patterns in Real Numbers
• 5.7.2: Comparing Graphs
  • 5.7.2: Self Check
  • 5.7.2: Additional Resources
• 5.7.3: Describing Graphs
  • 5.7.3: Self Check
  • 5.7.3: Additional Resources
• 5.7.4: Quantities that Change Exponentially

After that, you’ll practice and review.

• 5.7.5: Practice
• 5.7.6: Lesson Summary
