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.
