f(x) is a reflection over the y axis
f(x) is a reflection over the x axis Now, how do we represent a reflection over y=x?

Understood. My point was that you can't refer to it as f^{1}(x).

Let's see...a reflection over line y=x means [itex] (x_0,y_0)\rightarrow(y_0,x_0) [/itex].
It think it should be [itex]f^{1}(x)[/itex]...ohh...sorry...[itex]R^{1}(x) [/itex].
