# Editing a question based on accepted answer

Sometimes, a user will ask a vague question, and an answerer says "I don't entirely understand your question, but I will assume you mean ___." The answerer then includes a re-written version of the question and proceeds to answer it.

If the asker accepts this answer, would it be proper to edit the original question to fit this other interpretation by the answerer?

A concrete example: Finding the root, domain, and limit to infinity of $f(x) = xe^{-x}$
