Lesson 7: 3.8 Exponential Growth and Decay
Duration of Days: 2
Lesson Objective
Students will apply derivatives of exponential functions to real-world examples, such as population growth, compound interest, and radioactive decay.
1. What are some real-life examples of exponential growth? Exponential decay?
2. How is compound interest different from simple interest?
- exponential growth
- exponential decay
- relative growth rate
- half-life
(Differentiation Rules)
Exponential Growth/Decay:
DOK levels 1-4
population growth, continuously compounded interest, radioactive decay, ...
- students often struggle with the difference between growth rate and relative growth rate
