I have two functions:

[tex]

\begin{array}{l}

f(x) = \left\{ {\begin{array}{*{20}c}

{\pi - x\,for\,x \in (0,\pi )} \\

{0\,for\,x \in (\pi ,2\pi )} \\

\end{array}} \right. \\

g(x) = \left\{ {\begin{array}{*{20}c}

{x\,for\,x \in (0,\pi )} \\

{0\,for\,x \in (\pi ,2\pi )} \\

\end{array}} \right. \\

\end{array}

[/tex]

According to my book, then g(x) = f(-x-Pi). But when I insert, I get that g(x) = Pi-(-x-Pi) = 2Pi + x for x € (0, Pi)?
