Is there a common name for the growth rate of functions that are asymptotically on the order of $x^{cx}$, for some $c$? The term super-exponential is much too general. The factorial function grows in this way -- so would it be appropriate to say that similar real-valued functions have "factorial growth"?
Is there a common name for $O(x^{cx})$ type functions?

0That's right. In a similar way, $e^x$ grows much faster than $2^x$, but they're both called exponential functions. I'm looking for a catch-all term that describes all functions that grow as fast as $x^{cx}$, for some value of $c$. – 2012-07-17
