More Graphs of Functions

In this video lesson, students begin to analyze graphs of functions and use them to answer questions about a context. Students look at what happens over intervals of input values and learn that graphs can be viewed as dynamic objects that tell stories. They connect specific features of the graph with specific features of the contextual situation and investigate what happens over ranges of input values.  As students learn to interpret graphs in terms of a context and use them to answer questions, they learn an important skill in mathematical modeling (MP4).
