Is there standard notation to handle "chains of functions"?

Question

Let
$f(x)=g $

$g(y)=z $

Is there standard notation to express z in terms of f(x)? Something like (f(x))(y)?

Answer 1

I've always written $f(x)(y)$. In my opinion, it's clear that evaluation should be left associative, so no need for the extra set of parentheses. Some contexts (e.g. $\lambda$-calculus) would even just write $fxy$
