Lesson Narrative
In this lesson, students study exponential functions and their graphs in context. Given a graph or a description of a relationship, they write one quantity as a function of another and then use the function to answer questions about the context. They also produce graphs of exponential functions, paying close attention to the appropriate domain and range, which are both restricted by the context (MP2, MP6).
- Determine whether a graph that represents a situation should be continuous or discrete.
- Interpret graphs of exponential functions and equations written in function notation to answer questions about a context.
- Use function notation to describe an exponential relationship represented by a graph.
- Use graphing technology to graph exponential functions and analyze their domains.
