Videos, worksheets, solutions, and activities to help PreCalculus students learn how to apply and solve exponential functions.
Applications of Exponential Functions (Part 1)
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)
Errata: the video shows the amount of Berillium-11 left one hour later instead of one hour ago.
Applications of Exponential Functions (Part 3
Algebra Applications: Exponential Functions
In this episode of Algebra Applications, students explore earthquakes using exponential models. In particular, students analyze the earthquake that struck the Sichuan Province in China in 2008, months before the Beijing Olympics. This dramatic, real-world example allows students to apply their understanding of exponential functions and their inverses, along with data analysis and periodic function analysis.
