Is there a mathematical symbol to describe relationships or dependencies between components and results?

Let's say that a relationship - perhaps a tenuous one, but whatever - exists between an outcome and several (possibly independent, likely interdependent) components A, B, and C. That is, outcome O is dependent on A, B, and C (which may be dependent to some extent on each other, but I'm not sure that's significant for this question). How does one describe this mathematically?
Seems to me that you could simply write O = f(A,B,C) and be done with it under the assumption that the magic happens in f(), but is there a more precise way to describe the relationship between (A,B,C) and O?
I was considering using the ≝ symbol but I don't know whether that's the proper usage.
I have to get this right because I'll be presenting this relationship to a bunch of academics who will chew me up if they spot something wrong.
So - any advice? Should I skip trying to describe this as a mathematical model and use my words?
