Functions Modeling Change, 5th edition, by Eric Connally, Deborah Hughes-Hallett, Andrew M. Gleason, et al., is designed to accomplish the main goals of the Precalculus course: to build a solid mathematical foundation and prepare students for Calculus. The authors achieve this by using real-world applications and focusing on a small number of key topics, thereby emphasizing depth of understanding rather than breadth of coverage. The WebAssign component of this text includes instant student feedback on randomized questions and reading links to a FlexPaper eBook.
