Given that fx is a onetoone function determine f1 f1258 You

Given that f(x) is a one-to-one function, determine f^-1 (f(1258)). You have 1 attempt(s) remaining before you will receive a new version of this problem.

Solution

• Property of inverse functions: Let f be a one-to-one function with domain A and range B. The inverse function f 1 satisfies f 1 (f(x)) = x for every x in A

and f(f 1 (x)) = x for every x in B

here x = 1258

so therefore   f 1 (f(1258) = 1258
