I'm looking to find an expression for a function that looks like the following. I clearly need a piece-wise function but I can't quite think of how to write it. Does anyone have any suggestions? Thanks for your help.

$$f(x)= \begin{cases} x & (0 < x < 1) \\ 1-x & ( 1 < x < 2) \\ f(x-2) & (x > 2) \end{cases}$$
