Activity Overview
Students explore inequalities by entering inequalities using symbols, plot their graphs (including union and intersection shades), store (x, y) coordinate pairs as lists, enter inequalities with vertical lines in an X= editor, and trace points of interest (such as intersections) between functions.
Before the Activity
