Transforming Functions to Fit Data is a valuable resource for pre-algebra through precalculus teachers, including more than 20 blackline-master investigations of a variety of functions using Texas Instruments CBL™ or Casio™ EA-100 electronic data collection devices.

Transforming Functions to Fit Data: Mathematical Explorations Using Probes, Electronic Data Collection Devices, and Graphing Calculators


Students Work with Real Data

Transforming Functions is comprised of two levels of experiments. In the first level, students learn to collect and graph their data, work with tables and graphs, and answer both qualitative and quantitative questions about functions. These exercises are geared primarily toward pre-algebra and algebra students but can be used in more advanced classes as well.

In the second set of experiments, intended primarily for algebra and precalculus, students move on to using transformations to find a symbolic representation of the underlying function. Students learn that there are families of functions. Starting with a "parent" and using algebraic manipulations, students work toward a specific function that models their particular experiment. Activities are also provided that let students practice transforming functions to fit existing data before they experiment with their own.

Calculator Programs Included

Included with the book are diskettes in Macintosh® and Windows® format containing calculator programs for use with the appropriate link software for both the TI-82 and TI-83 calculators, as well as the Casio CFX-9850G and CFX-9950G calculators. (Even if you don't have the link software, the programs are short enough to be entered by hand.) There are also extra data sets you can use with the transformation practice exercises, or in lieu of collecting firsthand data.
