F of b minus f of a
WebOct 26, 2016 · It's not generally true that f(A − B) = f(A) − f(B). Consider the unique function f: {1, 2} → {0} and take A = {1, 2}, B = {2}. Then f(A − B) = f({1}) = {0}, whereas f(A) − f(B) = {0} − {0} = ∅. This fails exactly where your mistake is: we can indeed have f(A − B) ⊈ f(A) − f(B). Saying that y ∈ f(A − B) means y = f(x), for some x ∈ A, x ∉ B. Web5 Answers. Take y ∈ f ( A ∩ B). Then, by definition, there exists x ∈ A ∩ B such that y = f ( x); since x ∈ B, we have y = f ( x) ∈ f ( B). Equality does not necessarily hold. Take f: { 1, 2 } → { 0 } (the only possible map); take A = { 1 } and B = { 2 }. Then f ( A ∩ B) = f ( ∅) = ∅, …
