A Graphical Approach to Precalculus with Limits is a comprehensive textbook that weaves together fundamental algebraic concepts, function analysis, and an introduction to calculus through a visually driven methodology. The text starts by establishing a strong foundation in linear functions, equations, and inequalities before progressing through graph transformations, quadratic and polynomial functions, and the intricacies of rational, exponential, and logarithmic functions. It further explores systems, conic sections, trigonometry, and vectors, culminating in an accessible introduction to limits, derivatives, and definite integrals. Throughout, real-world applications and clear graphical representations empower students to bridge abstract mathematical theories with practical problem-solving scenarios.

Problem 1
Speed Limits The graph of $y=f(x)$ gives the speed limit $y$ along a rural highway after traveling $x$ miles. (Graph cant copy) (a) What is the speed limit at the 4 -mile mark? (b) Estimate the miles of highway with a speed limit of 30 mph. (c) Evaluate $f(5), f(13),$ and $f(19)$. (d) At what $x$ -values is the graph discontinuous? Interpret each discontinuity.
