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.
