WebSep 4, 2016 · 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.

WebProof: If x is in f (A1∩A2) then there is an element a in A1∩A2 such that f (a) = x. Then a is in A1 and f (a)=x so x is in f (A1). And a is in A2 and f (a)=x so x is in f (A2). So x is in f (A1)∩f (A2). It is the reverse containment that is not always true. In general it will require the function to be injective (one to one).
