Domain & Range
Be sure students realize that any picture (even 3d) can be created from points and/or mathematical equations. Spend time talking about their favorite 3d movies and explain they are beginning the process. You can connect this lesson to transformations by having students think about how to animate a graph. For example, in the graph above, think about how to make Bart's eyes move.

Activity 1  Predicting the Graph

Watch video of graph being created.

Activity 2  Identifying Domain & RangeSelect any graph. Students practice identifying domain and range for any part of the graph.
Be sure to discuss how estimates are made for domain and range values as well as the types of inequality symbols used. Encourage students to consider whether the domain or range of any part of the graph might be all real numbers.
