Hello all(adsbygoogle = window.adsbygoogle || []).push({});

Thses are my questions:

1. Prove that if A(x) is a one to one odd function, then A^(-1) (x) is also odd function.

2. If D(x) and R(x) are one to one functions, then

(DoR)^(-1) (x)=(R^(-1) o D^(-1) )(x)

I hope that someone will help me ^^
