The Function Analyzer is designed and developed by the Concord Consortium. The Function Analyzer examines the relationship between solving linear equations and graphing linear functions. Using a novel approach, the Function Analyzer represents the linear function in three ways: symbolic notation, dynamic graphing on a Cartesian grid, and as a virtual manipulative using growing and shrinking stacks of tiles to represent the changing value of y. The Function Analyzer develops the understanding of slope as a rate of change, not just a geometric understanding of "rise over run."
Innovative technology developed by the Concord Consortium permits networked users of our software to save with one click an image of any screen made with CC interactive software. They can then share their work with other networked users in real time or asynchronously.
