Designed for courses in Precalculus requiring the use of a graphing utility.

The goal of this text is to motivate students by highlighting real people facing real challenges finding real solutions. This book features real workers at Motorola, along with hundreds of applications and real data sets highlighting the relevance and scope of activities a student may encounter in life. Students are expected to find functions that fit the data and both construct and implement elementary mathematical models.
