Can you check if I got any questions wrong, please.

I am not sure about Q2, Q8 and Q9.

Fuck, I got 8/10 for this quiz.

Kudos for anyone who can tell me where I got wrong. Stupid Usyd won't let us review quiz.

I think q8 is wrong
there are functions where the derivative is undefined at certain values of x, because it makes like a sharp corner kinda thing
I'll see if I can find an example

Not sure about 9 and 10, but 7 could be wrong?

Omg, before I submit the quiz, no one reply. After I submit the quiz, so many replies. Why you play with my emotion like that?
