This entry text is designed to follow either the combined algebra or individual elementary and intermediate algebra texts. College Algebra follows a logical "see first, then do" progression. To reinforce the concept that graphical approaches are used most effectively along with algebraic approaches, the authors present an example first under the heading Visualizing the Solution. This shows students how to depict the problem using a graphing calculator and then estimate its solution. The text then presents an algebraic solution, called Determining the Solution.
