Big Ideas: An exponential function may be the best function for summarizing an inexact relationship between two quantities. The best-fit model for the exponential relationship can be found by using technology. This model can then be used to find unknown data points and make predictions. This lesson builds on students' skills with developing and analyzing exponential models for exact relationships. In this task, students will look at inexact data and use technology to develop two models, one linear and one exponential. They will then compare and contrast the linear and exponential functions. This lesson will prepare students for future work they may encounter in statistics. Vocabulary: scatter plot, best-fit line, residuals, exponential model, linear model Special Materials: Graphing Calculator
