can you open it now?

nope

I only have wordpad on this pc.

ok. let me post it one by one but its up to ten

1 Let X= {x,y} and
T=ϕ,X,x
.Determine the closed set
a)X
b) X,{y}
c)X,ϕ,y
d) x,y

take a screen shot and post the jpg.

ϕ means empty set

i choosed c

`\(\emptyset\)`

Should it say \(\mathcal{T}=\{\emptyset, X, \{x\}\}\)
?

yes that is the topology

the question is what are the closed sets?

\[\let X={x,y} and ....T={\emptyset,X,x} \] what are the closed sets

x is not a set here. should it say \(\{x\}\)?

may be it was a typo error. they din't close i think they out to

the only thing that is a set is X and it is closed.

The other choices are not sets.

assuming the the question was set correctly, what option should have been correct ?

These questions are all messed up, they dont make sense...

which implies that it out to be A

ok thanks

i think indiscrete topology

i.e {y} is not in T
