Let X be a set with an equivalence relation ∼. Let f : X/ ∼→ Y be a function with domain as the quotient set X/ ∼ and codomain as some set Y . We define a function ˜f, called the lift of f, as follows: ˜f : X → Y, x 7→ f([x]). We define a function Φ : F(X/ ∼, Y ) → F(X, Y ), f 7→ ˜f. (1) Is Φ injective? Give a proof or a...

Show that the given map is surjective. Please give a detailed, thorough formal explanation/proof. It's somewhat obvious it is surjective, but I don't know how to start the proof. We are supposed to take y element of codomain and show that there exists f(x) = y but where is the codomain and where is the domain? Somewhat confused since we have two binary structures. Thanks! 7.
