### Areteem II-A

Hello,

I was wondering if I could get an extension for this week's homework. Also, I'm sorry this is late, but I am not sure how to do 9.26.

Thank you,

Angelina

Hi Angelina,

I extended the HW until tomorrow night so you can still submit it if you have time.

For 9.26:

- In part (a), ranges of values will work. so you just want to describe which $x$ will work using inequalities, etc. I know we didn't solve 9.4(b) in class, but 9.26(a) is similar to that problem in terms of having ranges of values of $x$ that work.
- In part (b), we actually have that either (i) $\lfloor 2x\rfloor = 2 \lfloor x \rfloor$ as in part (a) or (ii) $\lfloor 2x\rfloor = $ something else (involving $2 \lfloor x \rfloor$), which we're looking for in part (b).

Hope this helps a bit!
