Best ResponseYou've already chosen the best response.0Should it say \(\mathcal{T}=\{\emptyset, X, \{x\}\}\) ?

Best ResponseYou've already chosen the best response.0the question is what are the closed sets?

Best ResponseYou've already chosen the best response.0sec, can you post a pic? I am not sure if I am getting everything. I think it is missing a bunch of \(\{,\}\).

Best ResponseYou've already chosen the best response.0x is not a set here. should it say \(\{x\}\)?

Best ResponseYou've already chosen the best response.0Sorry man, this all makes a huge difference. I cant answer without seeing the question. as it is posted it cant be answered. \(\{X,\{y\}\}\) is weird...

Best ResponseYou've already chosen the best response.0may be it was a typo error. they din't close i think they out to

Best ResponseYou've already chosen the best response.0the only thing that is a set is X and it is closed.

Best ResponseYou've already chosen the best response.0The other choices are not sets.

Best ResponseYou've already chosen the best response.0And if they are they are not subsets of the space X, and thus are not closed with respect to the given topology

Best ResponseYou've already chosen the best response.0These questions are all messed up, they dont make sense...

Best ResponseYou've already chosen the best response.0for something to be closed, they need to be a subset of the space, the only thing that was a subset of the space was the space itself.

Best ResponseYou've already chosen the best response.0yes, but the others are not even defined. I think where ever you got this, there is a problem with displaying all the characters.

Best ResponseYou've already chosen the best response.0the thing they call a topology is not even a topology, as a topology is a set, and must have parentheses around it.

Best ResponseYou've already chosen the best response.0since I assume there should be parentheses, well then I dont know if they mean for there to be parentheses on other things, and without that information this cant be answerd.

Best ResponseYou've already chosen the best response.0A space (X,Td) is called____________ if and only if (i) ϕϵ (ii) T contain open set whose compliment are finite sets discrete topology indiscrete topology cofinite topology metric topology

Best ResponseYou've already chosen the best response.0i think indiscrete topology

Best ResponseYou've already chosen the best response.0you are not listening when I tell you that I cant answer anything from that page. If you have something else I will gladly help, but theses questions are messed up. Ill check back tomorrow.

Best ResponseYou've already chosen the best response.0sir, in the first question i asked . i assume that the option B is not correct because ,it is not in T. right ?
