Regardless of the value of t you use??? It looks the same for all t?
Could you reproduce my picture for t=1/2?

I can reproduce Tommy's assertion that for t->0 it tends to abs.

Well for t->0 the exponent 2^t->1, we have then
\( f^{-n}(f^{n}(x)) \).
The effect might be quite similar to \( \sqrt{x^2}=|x| \) except you use the right branch of the inverse.
