WebPay attention to the domains, g(x) and f(x) can not both be in X, one must be the inverse. f = g^-1 and f^-1 = g s.t. g(f(x)) = x In your example f^-1(x) and g(x) are identical, that does not work. g(f(x)) = x not g^-1(f(x)) if g(f(x)) = f(x), then g is the identity function not the inverse. Hope this helps WebGiven a function f (x), f (x), we can verify whether some other function g (x) g (x) is the inverse of f (x) f (x) by checking whether either g (f (x)) = x g (f (x)) = x or f (g (x)) = x f …
