Precalculus: Graphs and Models is a comprehensive textbook that bridges theoretical math concepts with practical problem-solving. It guides students through essential topics such as the use of graphing calculators, linear, polynomial, and exponential functions, and the analysis of systems of equations using methods like Gauss–Jordan elimination. Foundational ideas in trigonometry—including angles, basic identities, and the Law of Sines—are also explored in depth, providing a solid basis for more advanced studies. Additionally, the text introduces sequences, series, and conic sections, illustrating how these mathematical models apply to both abstract and real-world problems.
