Not to split hairs, but syntactically f(x) is a function in many

As I understand it functional programming places specific requirements
on functions, i.e.referential transparency. So f(x) may or may not be
"functional".
x.f() is also a function, but it is a member of the object x, is
referred to as a 'method' of x, and uses the syntactical "dot"
notation object"dot"function for identification.
Functional programming is not about writing a programm with functions
(google it for more info). This may cause some confusion.
Your original post was about functions vs methods, which are identical
except some syntax detail. FYI, in python x.f() is equivalent to f(x).
In an OOP world one will prefer the x.f() form.
