The Inequality Graphing App adds enhanced features for graphing equations and inequalities, and displays the relationships between them. Using the Inequality Graphing application, you can:
•
Enter inequalities using relation symbols
•
Graph inequalities and shade the union and intersection regions
•
Enter inequalities (vertical lines only) in an X=editor
•
Trace points of interest (such as intersections) between relations
•
Store (x,y) coordinate pairs to lists for viewing and optimizing functions for linear programming
