Since a=a then there exist b1,b2∈ B s.t b1=b2. So for every a∈ A there exist atleast a value b∈ B ...
WebOct 2, 2014 · Let's consider a y ∈ f ( A 1) − f ( A 2). This implies two consequences: y ∈ f ( A 1) ⇒ ∃ x ∈ A 1 s.t. f ( x) = y. y ∉ f ( A 2) ⇒ ∀ x ′ ∈ A 2, f ( x ′) ≠ y. Since f ( x) = y ≠ f ( x ′), we derive that x ≠ x ′ for any x ′ ∈ A … WebMay 5, 2008 · Yes. You are done with 2a). That wasn't so bad, was it? If x is in the union of A1 and A2 then it's either in A1 or it's in A2, but not both since they are disjoint. So you can use either f or g (that you defined for 2a)) to map it into B1 union B2. It's no more complicated than 2a).
