The Fourth Edition of Yoshiwara and Yoshiwara's MODELING, FUNCTIONS, AND GRAPHS: ALGEBRA FOR COLLEGE STUDENTS includes content found in a typical algebra course, along with introductions to curve-fitting and display of data. Yoshiwara and Yoshiwara focus on three core themes throughout their textbook: Modeling, Functions, and Graphs. In their work of modeling and functions, the authors utilize the Rule of Four, which is that all problems should be considered using algebraic, numerical, graphical, and verbal methods. The authors motivate students to acquire the skills and techniques of algebra by placing them in the context of simple applications that use real-life data.

Features and Benefits

  • INVESTIGATIONS. Each chapter begins with an Investigation of an applied problem. Investigations allow guided explorations of open-ended modeling problems and are carried throughout the text.
  • RULE OF FOUR INTEGRATION. To illustrate the Rule of Four, functions are shown in a variety of problems through use verbal descriptions, tables of values, algebraic expressions, and graphs.
  • Real-life examples. Carefully chosen examples and exercises include authentic applications from a variety of disciplines.
