And what would the Equation be?

You just need a relationship that is all below the line y=-3 and goes from -infinity to infinity in the range. Also to make it *not* a function, have it cross back on itself so that a single value of x may have multiple values for y.

it cant be a circle though b/c then the function would not have all real numbers in its domain..

A circle?

you can try this one - it only misbehaves for a little while...
x(t) = t-cos(2t)
y(t) = -t^2 - 3.229 - sin(t)
t E (-inf,+inf)
(you could get the constant a bit better, but it's late here.)
