What is the generic term for domain & range?

  1. Sep 28, 2012 #1
    As I understand it, there are the terms:

    domain - variables that are input to a function

    range - the variable that is output to a function

    This works well in a canonical single equation system like z = f( x , y ), but breaks down in an implicit function or set of equations. I was wondering what the proper term is for all the variables that exist in any system of equations - whether they happen to be input or output for any particular equation.

    Locus if we a talking about geometry. Otherwise "solution set" or something similar.
