(This is because X ⊂ Y means every element of X is of Y; so to prove X ⊂ Y we take an arbitrary one out of X to see if that one is in Y .) Then by definition there is some x ∈ A ∩ B ensuring y = f ( x). Then note that x ∈ A ∩ B implies x ∈ A and x ∈ B, implying that f ( x) ∈ f ( A) and ∈ f ( B). So y ∈ f ( A) ∩ f ( B). Share
