WebNov 20, 2014 · For any y ∈ f ( f − 1 ( B), there exists x ∈ f − 1 ( B) satisfying y = f ( x). Clearly y = f ( x) ∈ B. For any y ∈ B, since f ( x) is an onto function, there is x ∈ X satisfying that f ( x) = y, i.e., x ∈ f − 1 ( y). So y = f ( x) ⊂ f ( f − 1 ( y)) ⊂ f ( f − 1 ( B)).

For f 2 ( x), the solutions are involutions. For f 3 ( x), the only answer is f 3 ( x) = x . For all other f n ( x), one solution is f n ( x) = x. My question: For n ≥ 3, is f n ( x) = x the only solution? If not, what are the solutions? Edit: @MattSamuel said that any involution works for an even n. jena thomas nitzsche https://the-traf.com

WebSep 4, 2016 · Instead, f − 1 here is called the inverse image, which is not a function Y → X but instead it takes subsets of Y to subsets of X. It's confusing, I know, that they have the same symbol f − 1 for both. Your description of f − 1 ( f ( x)) is a bit muddled, even though the reasoning is correct.

WebTheorem: f is not continuous. Proof: Observe that f is invertible, because f(f(f(f(x)))) = f(f( − x)) = x and so f ∘ f ∘ f = f − 1. Any continuous invertible function on R is either strictly increasing or strictly decreasing. If f is strictly increasing, then: 1 < 2 f(1) < f(2) f(f(1)) < f(f(2)) − 1 < − 2 contradiction!
