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). |

... y-intercept: Find the x-intercept: If x = 0, then If y = 0, then y = 3x + 4 . y = 3x +4 y = 3(0) + 4 Substitute 0 for x. 0 = 3x + 4 Substitute 0 for y. y = 4 Simplify. –4 = 3× Subtract 4 from both sides. The y-intercept is the point (0 ...
