High school — Use the properties of exponents to transform expressions for exponential functions, for example 1.15^t = (1.15^(1/12))^(12t) to reveal the equivalent monthly rate.
The skill that covers it
What a student should be able to do
- Write an exponential model from a starting amount and a percent growth or decay rate.
- Compute compound interest with n compounding periods per year, and continuous growth with e.
- Model half-life and population change, and find a growth factor from two readings.
- Compare models and rates, including the effective annual rate.
