Hello, i try to define a piecewise function in SYMB view like this :
   
In Plot view, i see F1(X) and F2(X) undefined :
   
How can i resolve this ? Thanks.

Use the piecewise function. | is used for variable substitution, not domain restriction. Use a [,] key press while in the last box to add more lines.

You could also use the old standby of (2*X)/(X<5) which works on any calculator if it has a piecewise operator or not.

Try entering the PIECEWISE expression in algebraic mode:

   

This will get the results you are looking for:
