Functions of Complex VariablesThe four complex numbers are in red. These are the four points that will be put into the function f, g, or h. That is, these four complex numbers are the "arguments" of the function. And the set of four complex numbers are called the "preimage" of the function. The function then maps these points into new points by applying the function. The resulting "image" is in blue. Use simple, small, integer values of s and t and see if you can predict what the image will be before actually revealing it.
