About This Worksheet
This medium-level worksheet contains 18 problems designed for 12th Grade students practicing exponential growth & decay models. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.
Exponential growth and decay models describe the most important quantitative patterns in science and finance — population growth, drug elimination, radioactive dating, viral spread, and investment returns. Facility with these models is a core quantitative literacy competency that applies throughout biology, chemistry, economics, and environmental science.
- Model exponential growth and exponential decay using appropriate formulas
- Solve for time, rate, or initial value given other quantities in growth and decay models
- Apply compound interest formulas for both periodic and continuous compounding
- Compare periodic and continuous compounding to determine effective annual rate
- Fit an exponential model to real data using two data points
How to Solve: Worked Example
- Read the problem carefully.
- Identify what is being asked.
- Use what you know to find the answer.
- Check your work.
