So I have two inputs put into my (Y=) values and both of the equal signs are "highlighted". Then when I go into the graph, only one equation shows up. Yes they are 2 different equations, one is a cubic and the other is a quadratic so they should look totally different. If I go to the table menu after viewing the graph, only 1 set of values appears and if I go back to the (Y=) menu, the Y2 equal sign isn't "highlighted" anymore either. Bottom line is that no matter what, only one equation shows up on the graph.
