As part of their hallmark developmental math series, this revision of Beginning and Intermediate Algebra continues the time-tested Lial/Hornsby commitment to helping students succeed. Designed to accommodate instructors and students who wish to eliminate the topic overlap between separate beginning and intermediate algebra books, this successful text integrates the appropriate topics in one book and features a flexible Table of Contents that can be adapted for a variety of course structures. One up-to-date strategy that has been incorporated involves the early introduction of graphing lines in a rectangular coordinate system and functions. Consistent with current teaching practices, this organization also allows the integration of interesting applications featuring real world data in the form of ordered pairs, tables, bar and line graphs, and equations. Chapter 4 introduces ordered pairs, graphing, and slope with a gentle introduction to the function concept using input-output relationships. Chapter 8 reviews and then extends the work with linear equations in two variables begun in Chapter 4 and provides additional discussion of functions, including domain, range, and function notation. Also consistent with this approach, graphs of quadratic equations are included earlier in the text when quadratic equations are solved rather than with the material on conic sections as in the previous edition. For added flexibility, a new appendix that reviews exponents, polynomials, and factoring is also included.
If you choose not to cover graphing linear equations and functions earlier as the new edition suggests, you can defer Chapter 4 and combine it with Chapter 8 as in the previous edition. Material on graphing in Section 5.1 can easily be omitted. Applied problems in Chapters 5-7 that refer to the function concept can be used without actually working through Chapter 4.
