W is a neighborhood basis of a point x $\in$ X if these holds except one.

2. anonymous

option A) ∀w$\in$W,w$\in$N(x)

3. zzr0ck3r

what is N(x)?

4. anonymous

option B) its an open set containing x

5. zzr0ck3r

that makes no sense....

6. anonymous

or neighborhood of x

7. zzr0ck3r

so for all w in W we have that w is ALL N(x)? or just some N(x)?/??????

8. anonymous

it is an option. allow me post the remaining . this one might be the odd one

9. zzr0ck3r

lol ok man

10. zzr0ck3r

they are not giving you options that do not make mathematical sense...

11. anonymous

12. anonymous

13. zzr0ck3r

you can do what you want man

If xϵA¯ , then there exists a sequence (xn) of A such that xn→x is only true if X is a(an)

15. anonymous

options are Countable Metrizable Hausdorff Separation

16. anonymous

17. anonymous

x element of a closed set A

18. zzr0ck3r

If you do not answer this question I will no longer help you. Why are you copying them from some other source and then pasting them into word?

23. anonymous

24. zzr0ck3r

26. zzr0ck3r

Are you using explorer?
