And one point in Y has been mapped to by two points in X, so it isn't surjective If a function is both surjective and injective—both onto and onetoone—it's called a bijective function A bijective function is a onetoone correspondence, which shouldn't be confused with onetoone functions Mathematical DefinitionLet's say we have some function f F and it's a mapping from the set X to Y so if I were to draw the set X right there that's my set X and then if I were to draw the set Y just like that we know and I've done this several videos ago that a function just associates any member of our set X so I have some member of my set X there if I apply the function to it or if we're dealing with vectors we · In mathematics, an injective function (also known as injection, or onetoone function) is a function that maps distinct elements of its domain to distinct elements of its codomain In other words, every element of the function's codomain is the image of at most one element of its domain The term onetoone function must not be confused with onetoone
