Do you know what the derivative of a 2nd degree function is?

no

yes

yes it does

ok

so it will be #2 in the second attachment?

I can see it on one of your drawings on the right! Do you?

Yes it will be number 2 ?

so to will have letter A

No, I've got C

I mean this (see image)
The parabola on the left (2nd degree function) has the straight line on the right as it's derivative.

so number one will be 1 with letter c?

I meant number 2 sorry

so 2C ?

Yes

okay

i thought we already did number 2

He was telling you number #1 is C. There musta been some confusion there c:

ohhh okay lol sorry

so number 2 will be f?

Yes!

okay :)

I think you got it!

number 3 looks funny

I think #2 is `e` actually :o hmm

It is down, up, down, up, so look for -,+,-,+

okay so number 3 will be A ?

okay thanks for the correction zep

so 3A ?

Yes, 3A

okay

so number 4 will be D?

Right again! Always decreasing, so looking for a derivative that is always negative...

okay

so i'm guessing number 5 will be 5B?

You guessed wrong...
Look at graph #5 and compare with #3

It behaves in the same way: dec, inc, dec, inc, so -,+,-,+

ok so it will be 5f

ohh ok

so letter A goes to two graphs? okay

That's the mean part of the question ;)

okay so how about the last one number 6?

It goes down, then up, then down, so for f' we have: neg, pos, neg

so it will be 6B

No, that goes a lot more from - to + etc.

(it is really simple)

ohh so it will f since it does go negative pos then neg

okay well thanks for your help
