Best ResponseYou've already chosen the best response.0Do you know what the derivative of a 2nd degree function is?

Best ResponseYou've already chosen the best response.0You 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).

Best ResponseYou've already chosen the best response.0No look at the first graph on the left. To the left of the yaxis, it is decreasing, to the right it is increasing.

anonymous

Best ResponseYou've already chosen the best response.0This means, for f' you are looking for a function that is negative on the left side of the yaxis and positive on the right.

Best ResponseYou've already chosen the best response.0so it will be #2 in the second attachment?

Best ResponseYou've already chosen the best response.0I can see it on one of your drawings on the right! Do you?

Best ResponseYou've already chosen the best response.0Yes it will be number 2 ?

Best ResponseYou've already chosen the best response.0so to will have letter A

anonymous

Best ResponseYou've already chosen the best response.0but 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

Best ResponseYou've already chosen the best response.0I mean this (see image) The parabola on the left (2nd degree function) has the straight line on the right as it's derivative.

Best ResponseYou've already chosen the best response.0so number one will be 1 with letter c?

Best ResponseYou've already chosen the best response.0I meant number 2 sorry

anonymous

Best ResponseYou've already chosen the best response.0Now try #2. See what it does: increasing, decreasing, increasing. So you're looking for a graph that is +, then , then +.

Best ResponseYou've already chosen the best response.0i thought we already did number 2

Best ResponseYou've already chosen the best response.0He was telling you number #1 is C. There musta been some confusion there c:

Best ResponseYou've already chosen the best response.0so number 2 will be f?

Best ResponseYou've already chosen the best response.0I think #2 is `e` actually :o hmm

Best ResponseYou've already chosen the best response.0It is down, up, down, up, so look for ,+,,+

anonymous

Best ResponseYou've already chosen the best response.0okay so number 3 will be A ?

anonymous

Best ResponseYou've already chosen the best response.0@zepdrix : you're right, I'm having trouble looking at three different pictures, @onegirl: sorry ;)

Best ResponseYou've already chosen the best response.0so number 4 will be D?

anonymous

Best ResponseYou've already chosen the best response.0Right again! Always decreasing, so looking for a derivative that is always negative...

Best ResponseYou've already chosen the best response.0so i'm guessing number 5 will be 5B?

anonymous

Best ResponseYou've already chosen the best response.0You guessed wrong... Look at graph #5 and compare with #3

anonymous

Best ResponseYou've already chosen the best response.0It behaves in the same way: dec, inc, dec, inc, so ,+,,+

anonymous

Best ResponseYou've already chosen the best response.0Oops, 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

anonymous

Best ResponseYou've already chosen the best response.0so letter A goes to two graphs? okay

anonymous

Best ResponseYou've already chosen the best response.0That's the mean part of the question ;)

anonymous

Best ResponseYou've already chosen the best response.0okay so how about the last one number 6?

anonymous

Best ResponseYou've already chosen the best response.0It goes down, then up, then down, so for f' we have: neg, pos, neg

anonymous

Best ResponseYou've already chosen the best response.0No, that goes a lot more from  to + etc.

anonymous

Best ResponseYou've already chosen the best response.0(it is really simple)

anonymous

Best ResponseYou've already chosen the best response.0ohh so it will f since it does go negative pos then neg

anonymous

Best ResponseYou've already chosen the best response.0Yes, it's 6F. I must admit this kind of question can be confusing, because you constantly have to switch from increasing , decreasing to +, .
