A best-selling text for developmental intermediate algebra courses, Intermediate Algebra, Sixth Edition, provides mathematically sound and comprehensive coverage of the topics considered essential in a basic college math course. The Aufmann Interactive Method ensures that students master concepts by actively practicing them as they are introduced. This approach is ideal for traditional and returning students in both classroom and distance-learning environments. The Sixth Edition features expanded and enhanced coverage of functions, with mapping of functions and illustrations of function machines. New graphing exercises also prompt critical thinking. Discussion of solutions of systems of equations in Chapter 4 has been expanded and enhanced to promote greater understanding of dependent, inconsistent, and independent systems of equations. Simplification of radical expressions now features perfect powers rather than prime factorization. New concept-based writing exercises encourage students to verbalize—and understand—concepts and new developmental exercises in many exercise sets further reinforce concepts and skills.
