- 1 decade agoFavorite Answer
A function is a relation from set A to B and for it to be a function every element in A must have an image in set B.The set A is the domain and
the set of all images of the elements of A which are in set B is the range...gud luck
eg:- A={1,2,3,4}
B={1,2,3,4,5,6,7,8,9,10,11,12,13,14,
15,16,17,18,19,20}
function F={(1,1),(2,4),(3,9).(4,16)}
domain=A={1,2,3,4}
range={1,4,9,16}

The domain is whatever the x values can be, the range is the result you get, or the y values
