I need some support in order to make the graph of $f(x)$ where $f(f(x))=e^x$. I'm also interested in the limits of $f(x)$ at +/-$\infty$. This function has really aroused my curiosity and I'd like to find out more information on it.

$\begingroup$ Are there any conditions on $f$ such as continuity or even differentiability? $\endgroup$Stefan Geschke– Stefan Geschke2012-08-08 11:19:15 +00:00Commented Aug 8, 2012 at 11:19
