Overview
A Graphical Approach to Algebra & Trigonometry covers functions through a consistent, 4part process. The authors ask you 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 fosters a deep visual and graphical understanding of math, solidifying a stronger connection to the mathematical world around us. Careful chapter layouts, exercises, review questions and chapter features give you a comprehensive roadmap for success in the course. The 7th Edition adds a new Unifying the Function feature after introducing each major class of functions; updates data throughout with new topics including active Twitter users, organic food sales and more; adds nearly 500 new or updated exercises; and much more.
