Graphing y'=y-x+1 on TI Nspire CX CAS

In summary, the conversation discusses how to graph the function y'=y-x+1 on a TI Nspire CX CAS calculator. The example provided is simple, but the individual is having trouble inputting the function into the calculator. They are advised to make sure the window coordinates are defined correctly and to try tracing the function. The individual was able to successfully graph the function once but was unable to replicate it again.

This looks like a good reference.

the example they use is simple. I can't input f(x)=y-x+1 into the calculator. when i try y1=y-x+1, nothing shows up on the screen

Are you sure you have the window coordinates defined such that the plot passes through it? What happens when you trace the function?

I'm not sure. But I did it and the graph showed up and then I mistakenly closed the document, I didn't change any settings but I wasn't able to do it again.
