But it is very natural idea. Suppose A is just one point so you can get rid of it's point since f is bounded. Now what would happen if you continue this process when A has more points, you just need to justify that this process will be terminated, so you need something equivalent to axiom choice Very Happy

Yes it's true. Maybe I'm not familiar enough with this type of proof just yet to feel that it's very natural. I just really wouldn't have thought about it... but I'll keep an eye out in the future Very Happy

Thanks for sharing this nice problem.

I like your avatar by the way. Is that how you feel these days? Laughing

The thread had gotten off-topic, so I put the other half in the Suggestions forum so others can find it.
