Applying Exponential Functions

Examples, solutions, videos, worksheets, games and activities to help PreCalculus students learn how to apply exponential functions.

Applications of Exponential Functions (Part 1)
Half-life, Simple Interest, Compound Interest
A number of examples of how exponential functions apply to exponential growth of bacteria, half-life of elements (exponential decay), the exponential decay of the value of new cars, or the growth rate of classic cars. The value of compound interest is also discussed.

Applications of Exponential Functions (Part 2)
Growth/Decay with Simple Interest
Errata: the video shows the amount of Berillium-11 left one hour later instead of one hour ago.

Applications of Exponential Functions (Part 3)
Growth/Decay with Compound Interest
