Definition of FUNCTION• A FUNCTION is a specialized RELATION,
with the stipulation that each domain element (typically designated by “x”) is paired with one and only one element from the range (typically designated by “y” or by “f(x)”.
• Example of a relation that is a function: {(2,3), (-2,3), (4,1)}
• Example of a relation that is NOT a function: {(2,3), (4,3), (4,1)}
