Algebra 2 (Class 58)
Lesson Title
3.1.5: What are the Connections
Overview
In the previous lessons students started an exponential-representations web. In this class students work to develop methods for finding a rule from a graph. As they find ways to write rules based on graphs, they will build a deeper understanding of exponential functions.
