With the Inequality app that comes preloaded on the TI-84 Plus family of graphing calculators, you can graph functions and inequalities of the form y ≤ f(x), y < f(x), y ≥ f(x), and y > f(x). You can even graph and shade regions formed by the union or intersection of several inequalities. You can also use this app to solve linear programming problems. If you don’t know what linear programming is, see the explanation in the linear programming section in this chapter.
