ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
Do you know what the derivative of a 2nd degree function is?

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
You know the following I guess: If f is decreasing, then f' is negative (and vice versa). If f is increasing, then f' is positive ( and vv).

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
No look at the first graph on the left. To the left of the yaxis, it is decreasing, to the right it is increasing.
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
yes it does
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
This means, for f' you are looking for a function that is negative on the left side of the yaxis and positive on the right.

so it will be #2 in the second attachment?
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
I can see it on one of your drawings on the right! Do you?
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
Yes it will be number 2 ?
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
so to will have letter A
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
No, I've got C
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
but you can't match a with c , it says to match the left with the right so it has to be a letter with a number

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
I mean this (see image) The parabola on the left (2nd degree function) has the straight line on the right as it's derivative.
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
so number one will be 1 with letter c?
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
I meant number 2 sorry
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
Now try #2. See what it does: increasing, decreasing, increasing. So you're looking for a graph that is +, then , then +.

onegirl Group TitleBest ResponseYou've already chosen the best response.0
i thought we already did number 2
 one year ago

zepdrix Group TitleBest ResponseYou've already chosen the best response.0
He was telling you number #1 is C. There musta been some confusion there c:
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
ohhh okay lol sorry
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
so number 2 will be f?
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
@zepdrix: thx
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
I think you got it!
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
number 3 looks funny
 one year ago

zepdrix Group TitleBest ResponseYou've already chosen the best response.0
I think #2 is `e` actually :o hmm
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
It is down, up, down, up, so look for ,+,,+
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
okay so number 3 will be A ?
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
@zepdrix : you're right, I'm having trouble looking at three different pictures, @onegirl: sorry ;)
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
okay thanks for the correction zep
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
so number 4 will be D?
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
Right again! Always decreasing, so looking for a derivative that is always negative...
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
so i'm guessing number 5 will be 5B?
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
You guessed wrong... Look at graph #5 and compare with #3
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
It behaves in the same way: dec, inc, dec, inc, so ,+,,+
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
ok so it will be 5f
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
Oops, look something went wrong with my last response. Because 5 and 3 behave in the same way, you have to choose the same derivative: 5A
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
so letter A goes to two graphs? okay
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
That's the mean part of the question ;)
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
okay so how about the last one number 6?
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
It goes down, then up, then down, so for f' we have: neg, pos, neg
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
so it will be 6B
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
No, that goes a lot more from  to + etc.
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
(it is really simple)
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
ohh so it will f since it does go negative pos then neg
 one year ago

ZeHanz Group TitleBest ResponseYou've already chosen the best response.2
Yes, it's 6F. I must admit this kind of question can be confusing, because you constantly have to switch from increasing , decreasing to +, .

onegirl Group TitleBest ResponseYou've already chosen the best response.0
okay well thanks for your help
