In this activity, students build a model to describe the relationship between the number of Starbucks locations in the United States and the number of years since 1992. Students then use that model to make predictions about the number of locations in 2015 and beyond. Students will also interpret the features of the graph in context.
In the process, students learn that not all rapid growth is exponential growth, and that another function type (logistic) may provide a better fit when finite resources come into play.
