This text investigates the foundational mathematical principles required to transition from algebra to calculus through the study of functions and their graphical representations. The authors, Demana and Waits, utilize a graphical approach to help students visualize algebraic concepts, emphasizing the connection between numerical, algebraic, and graphical data. The framework is designed to build a robust understanding of polynomial, rational, exponential, and logarithmic functions as a prerequisite for higher-level mathematics.

Educators and students frequently cite this text as a standard resource for high school and undergraduate preparatory mathematics. Experts highlight the clarity of the graphical methodology as a primary strength for students struggling with abstract algebraic concepts.
