The "formula" for the inverse is as easy as the integer closest to the rough approximation you can get from the asymptotics. It is the same as with $x^5+5x$: if you want to invert it on positive integers, the formula for the inverse function is merely $y\mapsto [\sqrt[5]y]$ for all sufficiently large $y$. | |
