My calculator shows ERR: INVALID when trying to calculate Y of graph
My calculator is a TI-84 Plus Pocket SE. Basically as the title says, let’s use Y=X graph as an example. If I have my window values of X set to Xmin = -10 and Xmax = 10, and I graph the function Y=X and use the “calc value” function to try to calculate for a x value beyond the X window values (for e.g x=11) I will get an ERR: INVALID.
Is it impossible to calculate y values for X that is beyond your currently set X window values? Or there is something wrong with my calculator settings and how do I correct it? Thanks alot.
Ist dies eine gute Frage?
