Inverse Variations and Their Equations

Students used handheld computers to graph a series of equations that resulted in a variety of graphs that looked very different from the graphs of linear functions. Most notably, the graphs show curved "lines" in opposite quadrants (like quadrants I and III or II and IV). We talked about the equations that represent inverse variations (xy = k) and their major features, including asymptotes.
