Can someone explain to me why for any operator A and functions f(x), g(x),(adsbygoogle = window.adsbygoogle || []).push({});

[tex](Af(x))^*g(x) = f^*(x)A^+g(x)[/tex]

Where "^+" denotes the hermitian conjugate of A.

I went to see the demonstrator about it and he couldn't explain/prove that result. Thx.
