Chapter 3 Functions

In earlier grades, students have defined and evaluated functions, and used them to model relationships. Now students graph functions and interpret the graphs in terms of the quantities related by the function. They sketch graphs based on verbal descriptions of the relationship between the quantities. In this chapter, students use a line to model the relationship between two numerical variables. Later, students will make more sophisticated models by fitting a linear function to a data set and evaluating how well the function models the data.
