Activities: Using graphs to introduce functions. (English)
Math. Teach. (Reston) 96, No. 2, 126-137 (2003).
One idea for linking the representations and highlighting the importance of graphs is to introduce the concept of function using graphs, or pictorial representations of functions. A natural progression exists from qualitative graphs to quantitative graphs to tables to equations. Students become comfortable with functions that are introduced using this progression. This article presents four activities that use this progression to introduce the theme of distance from an object as a function of time. (orig.)
