This textbook covers the major topics of college algebra with an emphasis on functions. The concepts of domain and range and graph properties are discussed for each type of function (linear, power, exponential, logarithmic, quadratic) and provide a way to visualize solutions to related equations. Application problems provide motivation for the topics and videos allow students to both hear and see a problem worked out step-by-step. In addition to end-of chapter quizzes and homework assignments, each chapter contains various “Knowledge Checks” that allow students to evaluate their understanding of big ideas and key concepts.
