# Precalculus: Functions and Graphs

@inproceedings{Swokowski1987PrecalculusFA, title={Precalculus: Functions and Graphs}, author={Earl William Swokowski and Jeffery Alan Cole}, year={1987} }

This latest edition in the highly respected Swokowski/Cole precalculus series retains the elements that have made it so popular with instructors and students alike: its exposition is clear, the time-tested exercise sets feature a variety of applications, its uncluttered layout is appealing, and the difficulty level of problems is appropriate and consistent. Mathematically sound, PRECALCULUS: FUNCTIONS AND GRAPHS, Tenth Edition, effectively prepares students for further courses in mathematics…
