To demonstrate a function which is not one-one but is onto |
|
Answer» This means that given any x, there is only one y that can be paired with that x. A function f from A to B is called onto if for all b in B there is an a in A such that f (a) = b. All elements in B are used. By definition, to determine if a function is ONTO, you need to know information about both set A and B. |
