Did any of you realise that Q 14 on the MC is undefined? (even though it doesn't affect the question)

Yes I normally do these types of question by putting all 6 expression in the calculato, and seeing which one matches up in decimal value to the 1st one.

So my normal careless-mistake proof method just got ruined by VCAA =/

EDIT: NVM, I just realised that I could replace the lower bound "0" with "0.0000000001" and then my method will work
