F f -1 x math
WebThe identity f − 1 ( f ( x)) = x follows by the definition of f − 1, but f − 1 only exists when f is bijective. – Carl Mummert Oct 24, 2011 at 11:34 1 @Kevin. You're confusing two things. The function f: R R defined by f ( x) = x 2 has NOT an inverse, since it's not injective: ( … WebFree functions calculator - explore function domain, range, intercepts, extreme points and asymptotes step-by-step

WebJul 27, 2024 · For f 1 ( x), the only solution is f 1 ( x) = x. 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.
WebDec 8, 2012 · let f (x) = 1/ (x^i)= x^-i (where ^ denotes exponent, and i is the imaginary constant sqrt (-1) ) f (f (x)) = (x^-i)^-i) = x^ (-i*-i) = x^ (-1) = 1/x So a solution exists for complex numbers. I don't know if there is a general solution sticking strictly to Real numbers.
