An
improvement to the method below is to DIVIDE by the conditions that specify the
domain:
Y1 =
(X^3 - 12X + 1) / ((X > -3) and (X < 3))
This
way, instead of getting 0 when you are out of range, the function will be
undefined (which seems to be the effect you were looking
for).
On a
related note, if you wanted to graph a piecewise defined function, you could do
it as follows.
Y1 =
(X^2)*(X <= 0) + (2X - 5) * (X > 0)
This
way, when X <= 0, the right hand side of the addition will be 0, and when X
> 0, the left hand side would be 0 instead.
