I think you need to be clearer on exactly what you want. What does it
mean to plot from -4*%i to 4*%i? Is it the straight line between them?
Some other curved path? And if f(x) produces a complex number, what to
you want plotted? The real part? The imaginary part? As a complex
point on the plane? Something else?
When you can answer these, I think you'll know how to plot what you want.
