FUNCTIONS AND CHANGE: A MODELING APPROACH TO COLLEGE ALGEBRA, Sixth Edition, is ideal for both non-traditional and terminal students taking college algebra, as well as those who may continue onto calculus. Graphing utilities, functions, modeling, real data, applications and projects develop students’ skills and give them the practice they need to not only master basic mathematics but apply it in future courses and careers. With a new, separate section on quadratic functions, additional emphasis on business applications, and new skill-building exercises and Excel activities, the sixth edition reinforces the authors' focus on connecting math in the real world, promotes mastery of the material, and fosters critical thinking.
