WebEvaluate the following proposed proof that (fog) (x) = x for every real number x. 1. We know that -1 ≤ cos (x) ≤ 1. Accordingly, if M is an arbitrary real number, then f (x) > M when x ≥ M + 1, and f (x) ≤ −M when x <-M - 1. Therefore lim f (x) = ∞ and lim f (x) = -0. x→→∞ 2. WebProof of Property 1 : Suppose that f -1(y1) = f -1(y2) for some y1 and y2 in B. Then since f is a surjection, there are elements x1 and x2 in A such that y1 = f (x1) and y2 = f (x2) . Then since f -1(y1) = f -1(y2) by the assumption, f -1(f (x1)) = f -1(f (x2)) holds.

WebIf f : A → B and g : B → C are two bijections, then gof : A → C is bijection and (gof)-1 = f-1og-1. fog ≠ gof but if, fog= gof then either f-1 = g or g-1 = f also, (fog) (x) = (gof) (x) = x. (gof) (x) is simply the g-image of f (x), where f (x) is f-image of elements x ∈ A. WebAs an alternate approach, you could let h be the restriction of f to the range of g --that is, h: g ( A) → C is defined by h ( b) = f ( b) for all b ∈ g ( A).
