Perhaps you meant:

Let [itex]E\subseteq \mathbb{R}[/itex]. Find a function [itex]f : E\rightarrow \mathbb{R}[/itex] that is one-to-one, onto, and continuous such that [itex]f^{-1} : f(E) \rightarrow \mathbb{R}[/itex] is not continuous.

Is this your question?

Yes, this is my question:smile:

Why don't you just type your question? All of the stuff you are doing with special fonts, centering, and font size is distracting.
