The right answer should be "no".

bwramsey commented 4 months ago

"yes" is correct for what it looks like the question is trying to ask, but it should be worded more clearly. Is this in the textbook or in an exercise? Could you post a link to the page?

if f(x) is invertible at x=0.5,then f^(-1)(f(0.5))=0.5,but f(0.5) is undefined.

bwramsey commented 3 months ago

f is invertible at the point. It does not say that the inverse was differentiable.
