HP Prime whats in the printing can be done.
Hello Everyone:
These two pics are in print the last one shows Prime doing this graphing kinda but: displays the HP 39 still it gives the impression, it can be done. However, that is not the case still waiting for further information. I believe it could until the last update. It may go back a few years let see. Do you have problems entering the Equation in the HP Prime? There should be no need for work around it in TextBook Style

I don't have problems entering the equations in the Prime but the values of F1(X) and F2(X) in the Plot view are NaN.
Here is how I would do it without the 'where' operator: You can also use the function PIECEWISE (see the oncalc help for more details): Note: in Textbook mode you can avoid specifying the second condition.

RE: HP Prime whats in the printing can be done.
The other way to do it is 2*MIN(1,X).
It's not elegant, but it should work. The other way to do it if you wanted a strict bound is to do (2*X)/(X<1).
