This is not a complete answer, but some help about .

In real numbers, is necessary. As x tends to 3 from the right, g becomes increasingly negative, ~~and this seems to be an asymptote~~ there is a horizontal axis intercept for x=3. Also a critical point occurs at x=5; in that for g to be defined, .

More theoretical stuff can be done, but....
