This text investigates the foundational principles of algebra and trigonometry through the lens of functional relationships. The authors, Marvin L. Bittinger and Mervin L. Keedy, utilize their extensive backgrounds in mathematics education to present a structured framework that emphasizes the concept of functions as the primary tool for understanding algebraic and trigonometric operations. By integrating clear definitions with systematic problem-solving techniques, the book provides a logical progression for students to master complex mathematical concepts.

Educators and students frequently cite this text as a reliable resource for building a strong mathematical foundation in pre-calculus studies. Experts highlight the clarity of the pedagogical approach, noting that the focus on functions helps bridge the gap between basic algebra and more advanced calculus topics.
