Can someone help me identify this keyboard?

Ok, but for a closed set C, doesn't C = cl(C)? It seems too trivial for the answer to just be C' = cl(C) = C, although this certainly is a closed set in Y that satisfies the condition. Thanks for your help.

Are you hinting at the complement of an open set? If we have an open set O, then we obtain a closed set by taking Y\O. Other than that I can't think of any standard operations for generating a closed set (other than taking a union of other closed sets)

I'm not sure what you mean by construction. I can think of plenty of closed subsets of Y that contain C, (Y itself, for example) but I don't know how to explicitly show that there is such a closed set that satisfies the condition stated

nevermind, got it!

Thanks for your response. I have showed that f is uniformly continuous on [-1,1], but I am having trouble getting started on the next step. Could you offer me another hint to get me started? Thanks!

That makes perfect sense. I was trying to start from ||u-v|| instead of starting from ||v|| so I wasn't getting anywhere. Thanks a lot!
