So X, Y = non-empty sets, and f = function (X,Y)
I have to show that
f(A and B) (c underlined) f(A) and f(B)
using element argument.
I have no idea - started with choosing x as a particular but arbitrarily chosen element of f(A and B) so now I have to show it is in either f(A) and f(B) but I dont know how! any help would be awesome, thanks!
