## Efficacy and Outcomes

### Reviews

"One of the best precalculus texts on the market . . . This is a wonderful text. Its strength is in the problems. I love the number and level of applications. The authors have also succeeded in designing a text for the use or non-use of the graphing calculator."

— Dana Undegrove, Bellevue Community College
