Precalculus: Functions and Graphs

Precalculus: Functions and Graphs, 4th Edition, by Mark Dugopolski, is a textbook published by Pearson to prepare students for precalculus courses. The text offers strategies designed to support the transition from algebra to subsequent calculus coursework.

Core subject coverage addresses equations, inequalities, and mathematical modeling. Topics examined include single-variable equations, relationships and graphs in two variables, quadratic equations, and complex numbers, alongside scatter diagrams and curve fitting.

To bridge foundational algebra and advanced mathematics, the textbook includes pedagogical tools such as Foreshadowing Calculus and Concepts of Calculus, which illustrate how algebraic topics connect to future calculus principles.
