##### X inequations on the Nspire
« on: January 18, 2012, 11:44:50 am »
Hey guys,

I was wondering how I can do x <= 4 and x > 1 inequations to be graphed on the Nspire? On the 84+ I know I can use Inequalz but what about on the Nspire...

Thanks.

press backspace when you are in the input bar and next to the f(x)=  in graphs and it will give you a list of options.

That only allows me to do stuff like y > 2. If I change the Y to an X, I get an Invalid Syntax error.

No,that is y = 2x, for all values of x <= 4.

But I want x <= 2 for example :S

I don't really know about that, but you could always just do y > 9999(x-3) for x < 3.
