Unifies the theme of a function – See, Solve, Apply

The Graphical Approach series by Hornsby, Lial, and Rockswold covers functions through a consistent, four-part analytical process. The authors ask students to:

1: [See] Examine the nature of the graph

2: Solve a typical equation analytically and graphically

3: Solve the related inequality analytically and graphically

4: Apply analytic and graphical methods to solve an application

This proven approach helps students gain a deep visual and graphical understanding of math, solidifying a stronger connection to the mathematical world around them.
