ON, also refers to the position of a motionless object.- The kitten is on the roof.I wonder how it got there. One-one and onto mapping are called bijection. "Into" is the word you use by default, and you can change it to "onto" if you're allergic to French or something*, so that you need to say that the function is surjective without actually using that word. By definition, to determine if a function is ONTO, you need to know information about both set A and B. I still can't figure out when to use on and onto, e.g.,"He put the bag on/onto the table". On to Meaning and Examples All elements in B are used. Let us now discuss the difference between Into vs Onto function. Check whether y = f(x) = x 3; f : R → R is one-one/many-one/into/onto function.

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. Onto mapping are also called surjection.
