Description and Additional Formats:

This image represents the real part of the complex square root relation, the inverse relation for the complex squaring function.

Notice that the surface seems to intersect itself, and that lines parallel to the red axis intersect the surface at two points (so the relation is multiple-valued, and hence not a function).
