    You have to use the when-command :

    Type at the y=-editor:

    y1(x)= when(x<4,0,when(x<6,x-2,0),0)

    You find the "when("-command at catalog+ . at the first place.

    (You probably know that the TI-89 switches into text mode so the . - key [in words: point key] means the character W)

    I've attached the screenshots of the inputscreen and the graph.
