## Domain, co-domain and range of function

Domain, co-domain and range of function https://www.youtube.com/watch?v=FdK9_Fp76cw If a function f is defined from a set A to set B then for f : A ⟶ B set A is called the domain of function f and set B is called the co-domain of function f. The set of all f-images of the elements of A is called the range of function f. In other words, we can say Domain = All possible … [Read more...] about Domain, co-domain and range of function
