Question

Define onto into fraction​

Answer 1

Answer:

An "onto" function, also called a "surjection" (which is French for "throwing onto") moves the domain A ONTO B; that is, it completely covers B, so that all of B is the range of the function. Formally, for every point y in B, there is some point x in A such that f(x) = y

Answer 2

Onto function could be explained by considering two sets, Set A and Set B which consist of elements. If for every element of B there is at least one or more than one element matching with A, then the function is said to be onto function or surjective function. The term for the surjective function was introduced by Nicolas Bourbaki.
