How do you verify if #f(x)=x^5; g(x)root5x# are inverse functions? Precalculus Functions Defined and Notation Function Composition 1 Answer Somebody N. Jul 14, 2018 See below. Explanation: If #f(x)# and #g(x)# are inverses, then: #f(g(x))=g(f(x))=x# #(root(5)(x))^5=(root(5)(x^5))=x# #x=x=x# So #f(x)# and #g(x)# are inverses.
