Exponential growth functions | Exponential and logarithmic functions | Algebra II | Khan Academy
By Khan Academy
Watch this introduction to exponential growth functions, including the form of an exponential function, an exponential input output table, the graph of an exponential function, and scenarios modeled by exponential growth.
Linear Quadratic and Exponential Models
By Khan Academy
Watch this video to learn how to identify linear and exponential functions from input output tables. Linear functions grow by equal differences over equal intervals so as x increases or decreases at a constant interval you add or subtract a constant for each corresponding y interval. Exponential functions grow by equal factors over equal intervals so as x increases or decreases at a constant interval you multiply or divide a constant for each corresponding y interval.

Algebra Applications: Exponential Functions
By Media4Math
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. Segments include: What is an earthquake? The basic definition of an exponential function is shown in the intensity function for an earthquake. Students analyze data and perform an exponential regression based on data from the Sichuan earthquake. What is the difference between earthquake intensity and magnitude? An exponential model describes the intensity of an earthquake, while a logarithmic model describes the magnitude of an earthquake. In the process students learn about the inverse of an exponential function. How is earthquake magnitude measured? An earthquake is an example of a seismic wave. A wave can be modeled with a trigonometric function. Using the TI-Nspire, students link the amplitude to an exponential function to analyze the dramatic increase in intensity resulting from minor changes to magnitude.
