Nov 6, 2011 at 20:18 comment added Gerald Edgar You can think of this as an iterated function system, defined on the compact space $[-\infty,+\infty]$ defined by the two maps $e^x$ and $−e^x$ (extended to the compactification by continuity). Using the compactification means that we do include points like $0$, but those points have two different representations.
