1. Graph Exponential Decay Functions
Lesson 7.2
Graph Exponential Decay Functions

2. Objective
Graph and use exponential decay functions

3. Standards
12.0 – Students know how the laws of fractional exponents , understand exponential functions, and use these functions in problems involving exponential growth and decay

4. Academic Language
Exponential decay function
Decay factor

5. Think/Pair/Share
What is the difference between a growth function and decay function?

7. Use the backup plan and compare to the parent function

8. Transformations
Create a small list of transformation starting with the parent function. Make it detailed so you can use it in class, on homework, and on quizzes.

9. Practice

10. Exponential Decay Model
*What difference do you notice when compared to the exponential growth model?
