PROFESSIONAL COMMENTARY

This activity has students look for functions within a given set of data. After analyzing the pattern of the data, students should be able to determine a type of function that best represents the data. Students then have the opportunity to generate their own data in a number of different problem situations and, using graphing calculators, to find the curves of best fit. Student activity sheets are included, along with interactive Internet extensions. This lesson plan first appeared in the September 1993 issue of Mathematics Teacher. (author/sw)
