restraints in graphs.



well.. let's say i have y=3. how to u make it so it stops at x=3? i
made an equation like ... y=3 (x<3).

however,it made two lines, this is w/o the axis it makes 2 lines...
if not then the 2nd line blends into the x axis.

kinda like this:

y = 3 -----------
                 \
                  ----------- y=0

why does it do that, and how can i fix it?

thanx.
