I'm sure parisse has more to say, but as I understand it, a mathematical function \( f(x) \) is represented in the CAS as f(x):=x^2 or f:=(x)->x^2. Typing f(x):=x^2 is the same as typing f:=(x)->(x^2). On the other hand, if we use f:=x^2 then we have simply created a variable named f whose content is the expression x^2.
