http://www.baibeike.com/wenda_2126184/ WebSep 3, 2016 · Your proof looks pretty good. 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. jerome boateng brillen collection https://conestogocraftsman.com

Proof: 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 ... jerome bixby writer

If f is both surjective and injective, then f is bijective. Let X be a nonempty set.

WebProposition 4 All sets with µ∗(E) = 0 are µ∗ measurable. Proof. If µ∗(E) = 0, then for an arbitrary set A⊂Xwe have µ∗(A) ≥µ∗(A\E) = µ∗(A\E) + µ∗(A∩E) {z } 0, because A∩E⊂E. Let M∗ be the class of all µ∗-measurable sets. Theorem 5 (Carath´eodory) M∗ is a σ-algebra and µ∗: M∗ →[0,∞] is a measure. Proof. We will split the proof into several steps.
