This text investigates the foundational mathematical concepts required for calculus through the integration of algebraic manipulation and graphical representation. The authors, all experienced mathematics educators, utilize a structured pedagogical approach that emphasizes the connection between symbolic equations and their visual counterparts on a coordinate plane. By focusing on the 'graphs and models' framework, the book provides students with the necessary tools to visualize functions and interpret mathematical data effectively.

Educators frequently utilize this text as a standard resource for undergraduate preparatory courses due to its clear, methodical progression of topics. Experts highlight the book's emphasis on visual learning as a primary strength for students transitioning into higher-level calculus coursework.
