This text investigates the core principles of precalculus by prioritizing visual representation and graphical analysis over traditional algebraic manipulation. Authors Bert K. Waits and Franklin D. Demana utilize their extensive backgrounds in mathematics education to construct a framework where students use graphing technology to explore functions, equations, and inequalities. By integrating visual data with symbolic logic, the authors argue that students develop a more intuitive understanding of mathematical relationships. The text serves as a bridge between foundational algebra and the rigorous requirements of calculus.

Educators and students frequently cite this text as a foundational resource for transitioning into calculus through a visual-first pedagogy. The prose is noted for its academic density and structured approach to complex mathematical concepts.
