Question 456752: can you explain why f represents the graph of a function

It's just standard notation to denote a function in terms of x as f(x). I guess mathematicians chose f since function begins with f. Note that f is not a variable on its own, and other letters could denote other functions (e.g. h(x), zeta(x)).
