Concepts of Intermediate Algebra: An Early Functions ApproachBrooks/Cole Publishing Company, 1996 - 706 páginas This comprehensive book from Dave Gustafson is perfect for a one-semester course where early coverage of graphing and functions is used to explore the mathematics and applications. All the topics generally found in a one-semester intermediate algebra course are here, but with a modern twist: Gustafson emphasizes conceptual understanding, early treatment of graphing, problem solving, and use of technology (graphing calculators). |
