Question

If G-1(x) is the inverse of G(X), what is the value of G-1(G(x))?A. 1B. x^-1C. OD. X

Answer 1

If two functions are inverses, then each will reverse the effect of the other. The composition of a function and its inverse is:

`f(f^(-1)(x))=f^(-1)(f(x))=x`

Then, for the given functions:

`G^(-1)(G(x))=x`
