Reflection: Complex Tasks Inequalities: The Next Generation - Section 2: Share


Here is an image showing a graphical solution from one group. This group originally used the algebraic solution but then tried to look at the graph to try another method. The graph seemed to make the most sense to students and was most commonly used to "check" the algebraic solution.

A problem arose when students were working on inequalities involving rational functions - it was difficult to look at the graph on the graphing calculator because the resolution was too poor. In this case the sign diagram seemed to be the best strategy.
