VIDEO: 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, realworld example allows students to apply their understanding of exponential functions and their inverses, along with data analysis and periodic function analysis.

VIDEO: Algebra Applications: Exponential Functions, Segment 1: Introduction 
In this introductory segment students learn about the great earthquake of 2008 that hit the Sichuan province of China. In the process they learn about how exponential functions provide a good model for describing earthquake intensity.

VIDEO: Algebra Applications: Exponential Functions, Segment 2: 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.

VIDEO: Algebra Applications: Exponential Functions, Segment 3: 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.

VIDEO: Algebra Applications: Exponential Functions, Segment 4: 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 TINspire, students link the amplitude to an exponential function to analyze the dramatic increase in intensity resulting from minor changes to magnitude.

VIDEO: Algebra Nspirations: Exponents and Exponential Functions 
Almost everyone has an intuitive understanding that exponential growth means rapid growth. Written and hosted by internationally acclaimed math educator Dr. Monica Neagoy, this video builds on students’ intuitive notions, explores exponential notation, and analyzes properties of exponential function graphs, with the help of TINspire features such as sliders and graph transformations. Using exponential functions to model finance applications and a Newton’s law of cooling problem further help students build a solid foundation for these fundamental algebraic concepts. Concepts explored: functions, exponents, exponential functions.
