@ManImStumped please help me!!

OpenStudy (anonymous):

@Kainui please help me :'((

OpenStudy (freckles):

I would look at the green curve first...and then look at the other curves and see if they are f' and f'' if that is f

OpenStudy (freckles):

Notice it is increasing until we get to 1.5 then there sorta like a vertical line almost there the slopes after that should appear to you like the slopes are getting closer to 0 then after than again it looks like we kinda sorta have a vertical line again at 4.7 maybe... But that is decreasing and decreasing after the vertical-ish part... I hope this is a hint on how you should determine f'... And then you can determine f'' from f'

OpenStudy (anonymous):

@freckles ohh so it would be D right?

OpenStudy (anonymous):

@perl @amistre64

OpenStudy (anonymous):

@e.mccormick HELP

OpenStudy (anonymous):

@MIA305DT

OpenStudy (amistre64):

how would you define the relationship between f f' and f"

OpenStudy (anonymous):

uhh

OpenStudy (amistre64):

what is your concept of derivatives is all

OpenStudy (anonymous):

youre asking me what derivatives are?

OpenStudy (amistre64):

yeah, fundamentally what are they?

OpenStudy (anonymous):

a slope of a curve or a rate of change

OpenStudy (amistre64):

yeah and the graphs are really not that easy to descern for me but, we are more interested in +,- and 0 for f' instead of the actual values

OpenStudy (amistre64):

notice A, it looks to be curving upwards at the left, so its derivative would have to be + and moving until it changes direction

OpenStudy (anonymous):

okk

OpenStudy (amistre64):

when A changes about and starts heading down, we need a - value to me, it looks like C is defining the slope of A C = A' to me

OpenStudy (anonymous):

ok gotcha so far

OpenStudy (amistre64):

can we narrow the options? when that has A to C?

OpenStudy (anonymous):

wait so it is not D?

OpenStudy (amistre64):

it could be D according to the A then C setup but i cant place B in front of A at the moment

OpenStudy (amistre64):

its trying to match curves thats a pain :) A and C are related, and it looks to me that A can define the slope of C as well C to A seems a good option to me now that i stare at it more lol

OpenStudy (amistre64):

it B that just doesnt really fit the bill for anything to me, so im most prone to pick the first option :)

OpenStudy (amistre64):

B moves its slope as +++++ undefined+++++++0--------- B moves how C is defined

OpenStudy (anonymous):

you think that the answer cannot be determined?

OpenStudy (amistre64):

but A does not move how B is defined B = ------0++++++++++++0---------- A = ++++undefined++++++++0------

OpenStudy (amistre64):

i cant see a solution that satisfies it. if we try to back solve it ... test out if the options make sense

OpenStudy (anonymous):

okk

OpenStudy (anonymous):

@jim_thompson5910

OpenStudy (amistre64):

AB is not a good fit CA is good, is AB? no, we already determined that AB is bad BA is bad ... so those 3 options just dont work for me

OpenStudy (freckles):

The only reason I told you to start with green curve is because it would no sense otherwise to me that is. Green was continuous but not differentiable at those two particular spots I talked about so you will have va there for the derivative. We cannot start with a non-continuous function (well at those two points) and take derivative and somehow get a continuous function (at those two points)

OpenStudy (freckles):

Both of the other two curves were non-continuous at those points.

OpenStudy (amistre64):

its all about trial and error to me :)

OpenStudy (freckles):

it looks like they don't have the right choice listed

OpenStudy (anonymous):

So i guess it would have to be A(:

OpenStudy (amistre64):

assume an option is right, and show that its wrong ... in the end, the only one left standing has to be the solution

OpenStudy (freckles):

well the answer can be determined it is just not listed

OpenStudy (amistre64):

6 possibilities? any of them make sense?

OpenStudy (amistre64):

abc acb bca bac cab cba i dont think any of them fit well enough

OpenStudy (freckles):

do you know which is the right combination i was going to put it but i took away

OpenStudy (freckles):

I want you to tell me @mondona

OpenStudy (freckles):

and it doesn't have to be a choice listed

OpenStudy (amistre64):

ab and ba are simply not doable permutes acb bca these are the only possible ones, and i havent tried them

OpenStudy (anonymous):

but those are my only choices lol

OpenStudy (freckles):

I disagree with your possible choices

OpenStudy (freckles):

The question itself was messed up anyways

OpenStudy (freckles):

it said f , f' and f'

OpenStudy (freckles):

not f, f', and f''

OpenStudy (amistre64):

the double tick was line feed

OpenStudy (freckles):

question messed up so so could answers be

OpenStudy (freckles):

oh on next line

OpenStudy (freckles):

i'm a goofy

OpenStudy (anonymous):

so my possible answers are right?! hahahha

OpenStudy (freckles):

Well I still say they are wrong

OpenStudy (freckles):

I have the choice in my head and I badly want to tell you because answer isn't listed

OpenStudy (freckles):

But I want you to say it first.

OpenStudy (anonymous):

nevermind guys, just drop it lol im putting A

OpenStudy (amistre64):

cb is bad that leaves bca which i cant see anything particulalriy wrong with

OpenStudy (freckles):

bca !!! all the way

OpenStudy (freckles):

I guess you have to put a choice don't you mondona? Like this online homework?

OpenStudy (amistre64):

good luck all the same ;)
