"WebA function is a special type of relation . A relation is just a set of ordered pairs ( x, y) . In formal mathematical language, a function is a relation for which: if ( x 1, y) and ( x 2, y) are both in the relation, then x 1 = x 2 . This just says that in a function, you can't have two ordered pairs with the same x -value but different y -values. " - How to know if y defines as a function of x
