The only thing to point out is when you said: By the definition of inverse function, f − 1 ( f ( x)) = { x ∈ X such that y = f ( x) }. Thus x ∈ f − 1 ( f ( A)). Two comments on this: This isn't usually called the inverse function -- we reserve that for when f is invertible, and has a function f − 1: Y → X.
