With a visual, graphical approach that emphasizes connections among concepts, this text helps readers make the most of their study time. The authors show how different mathematical ideas are tied together through their zeros, solutions, and "x"-intercepts theme; side-by-side algebraic and graphical solutions; calculator screens; and examples and exercises. By continually reinforcing the connections among various mathematical concepts as well as different solution methods, the authors lead readers to the ultimate goal of mastery and success. Basic Concepts of Algebra. Graphs, Functions, and Models. Functions, Equations, and Inequalities. Polynomial and Rational Functions. Exponential and Logarithmic Functions. Systems of Equations and Matrices. Conic Sections. Sequences, Series, and Combinatorics. For all readers interested in college algebra.
