Monotonic decreasing : (x)= e^(-x)
Strictly monotonic increasing: f(x) = e^x
Strictly monotonic increasing: f(x) = e^x

I have no idea what you mean by "unique" in this context or why an x^3 term would make it not "unique". Does that mean you don't want a polynomial? You don't want any powers of x at all?
That doesn't leave much if so, except e^x which is monotonic increasing on all x, and e^(-x) which is monotonic decreasing on all x.
