A Graphical View of Domain and Range, Inequalities, and Equations.

Laughbaum, Edward D.

The advent of calculators for graphing and function plotters is changing the way college algebra and calculus are taught. This paper illustrates how the machines are used for teaching the following: (1) domain and range; (2) product and quotient inequalities; and (3) the solving of equations. Instructional hints are provided for each topic with some equations and graphs. (YP)
