Answer 9

does any one actually know how to do this?

Answer 10

yes. the key is knowing what the various symbols mean. [ ] mean include the endpoints, and ( ) mean all but the endpoints.

\[[a,b]\]is the same as \[a\le x \le b\]because we include the endpoints of \(a\) and \(b\)

\[(a,b)\]is the same as \[a \lt x \lt b\]because we do not include the endpoints

Answer 11

I forgot to mention that you can of course mix and match the symbols as needed. I agree with your choice of C as the correct answer.
