Enhancing a Tradition of Success
We take great satisfaction from the fact that more than 100,000 students have learned
college algebra or precalculus from a Barnett Series textbook. Ray Barnett is one of
the masters of college textbook writing. His central approach is proven and remains
effective for today’s students.
The third edition of Precalculus: Graphs and Models has benefited greatly from
the numerous contributions of new coauthor Dave Sobecki of Miami University Hamilton.
Dave brings a fresh approach to the material and many good suggestions for
improving student accessibility. Every aspect of the revision focuses on making the
text more relevant to students, while retaining the precise presentation of the mathematics
for which the Barnett name is renowned.
Specifically we concentrated on the areas of writing, worked examples, exercises,
technology, and design. Based on numerous reviews, advice from expert consultants,
and direct correspondence with many users of previous editions, we feel that this edition
is more relevant than ever before. We hope you will agree.
