Classification of common functions types I'm trying to classify functions types. The problem is that english is not my native language and I'm not sure if I did it correct. According to my classification we could have the following functions types:
$$ N! -> Factorial $$
$$ 2^N ->Exponential $$
$$ N^2 ->Quadratic $$
$$ N * log N  -> Loglinear $$
$$ N  -> Linear $$
$$ \sqrt N  -> Sublinear $$
$$ log N  -> Logarithmic $$
$$ 1  -> Constant $$
Is it right function types names or not?

They all look right to me, except for "loglinear", as I note in the comments. 
As for $n\log n$, I'd call it $n\log n$. There is some (inconclusive) discussion at https://cs.stackexchange.com/questions/76317/what-is-the-name-the-class-of-functions-described-by-on-log-n (which at the very least shows that you aren't the only one interested in this question).
