Revised tests for the imageset especially for rational tuples Example    z = Interval(1,2)*Interval(2,3)*Interval(0,3) [1] Tuple(3,1,0) in imageset(Lambda((a,y,x),(y,a,x)),z) 	This should return True.
Revised tests for the imageset especially for rational tuples
Example
   z = Interval(1,2)*Interval(2,3)*Interval(0,3)
[1] Tuple(3,1,0) in imageset(Lambda((a,y,x),(y,a,x)),z)
	This should return True.

[2] Tuple(S(1)/3,1,0) in imageset(Lambda((a,y,x),(1/y,a,x)),z)
	This should return True.
