The Enhanced Edition of Swokowski and Cole’s PRECALCULUS: FUNCTIONS AND GRAPHS retains the elements in the Twelfth Edition that have made it so popular with instructors and students alike: clear exposition, an appealing and uncluttered layout, and applications-rich exercise sets. It also features an additional chapter on Limits (Chapter 11) and an Appendix V that includes proofs related to this new chapter. The excellent, time-tested problems have been widely praised for their consistency and their appropriate level of difficulty for precalculus students. The book also provides calculator examples, including specific keystrokes that show students how to use various graphing calculators to solve problems more quickly. This Enhanced Edition features updated topical references and data and continues to be supported by outstanding technology resources. Mathematically sound, this book effectively prepares students for further courses in mathematics.
