Question

HELP!!!!! MEDALS!!!!! WILL BE YOUR FAN!!!!!!!

Answer 1

Gordon is evaluating some stocks he wants to purchase. You can see the function of the stock price below. The variable x represents days.

Stock A B C
Price
A.) f(x) = 25(1.08)x
B.)
x f(x)
0 22.00
1 21.56
2 21.13
C.) The initial price of this stock is $30, but it has been increasing 4% each day.
1.) Create the price function for Stock D. It should have the second lowest starting price and the second highest rate of growth. Using complete sentences, justify that your function meets these requirements.
2.) Graph the price function for Stock D. Explain the key features of the graph with complete sentences.
3.) A recent drop in sales has affected Stock D with the function g(x) = –6. Explain to Gordon how Stock D’s new price function, f(x) + g(x), will be created. Graph f(x) + g(x).
4.) Gordon wants to fully understand what kind of changes could affect the money he is investing. Using complete sentences, explain the effect of the following transformations. Graph them and f(x) on the same coordinate plane.
f(x + 2)
f(–x)
f(x) + 3

Answer 2

@MERTICH

Answer 3

ya, keep holding, I am still on it

Answer 4

Ok

Answer 5

i think i answered part C.

Answer 6

in your old question.

Answer 7

bring it @undeadknight26 , this question has been a prob from yesterday.

Answer 8

kk let me see old question...

Answer 9

since it started at 30 your first step will be to create the first part of ur exponential function:
f(x) = 30(???)
since we know it increases by 4%.
so f(x) = 30(1.4)x

Answer 10

this should be it...

Answer 11

Are you sure??

Answer 12

quite sure not 100%...
@skullpatrol is this right?

Answer 13

thing is, it should have the second lowest starting price........and from the way I see it, according to your equation, starting price is 30. The function is for C, from the way I see it

Answer 14

Js @undeadknight26 C is a stock

Answer 15

It says that the starting point is: 30
The initial price of this stock is $30, but it has been increasing 4% each day.
1.) Create the price function for Stock D. It should have the second lowest starting price and the second highest rate of growth. Using complete sentences, justify that your function meets these requirements.
so you use that starting point.

Answer 16

Yea, for Stock C

Answer 17

C.) The initial price of this stock is $30, but it has been increasing 4% each day.

Answer 18

exactly...
so if u put just .4 percent it would start decreasing.that is why u put the 1.4.

Answer 19

that is how i see it at least...

Answer 20

ya, I agree that if we were to get the price function for Stock C, the one you gave is the correct one. It explains the behavior of the price for stock C. They want one for D. I don't see any data for D, but I suppose we have to find it somewhere from the behavior of the other stocks, may be the graph.And I suspect that the key is in the graphs.....

Answer 21

What is the question for D?

Answer 22

All of them

Answer 23

1.) Create the price function for Stock D. It should have the second lowest starting price and the second highest rate of growth. Using complete sentences, justify that your function meets these requirements.
2.) Graph the price function for Stock D. Explain the key features of the graph with complete sentences.
3.) A recent drop in sales has affected Stock D with the function g(x) = –6. Explain to Gordon how Stock D’s new price function, f(x) + g(x), will be created. Graph f(x) + g(x).
4.) Gordon wants to fully understand what kind of changes could affect the money he is investing. Using complete sentences, explain the effect of the following transformations. Graph them and f(x) on the same coordinate plane.
f(x + 2)
f(–x)
f(x) + 3

Answer 24

@undeadknight26 , the question in 1 is: Create.......for Stock D.

Answer 25

well lets just make one up.
f(x) = 28(1.3)

Answer 26

there is our function for part D.

Answer 27

ha ha ha. I want you to help me here at @undeadknight26 . we can do this. look carefully at the Stock B, what is its price function., Price dropped by 44c, then 43c, may be it will drop by 42 .....what is the function there? Also, the Start price for A is 27, for B is 22, for c is 30, so Start price for [should be second lowest] can only be between or given by 22<startpriceD<27,

Answer 28

How do I find the start price though?

Answer 29

ya,"WE" are still working on that. www.mathisfunforum.com/viewtopic.php?pid=295211#p295211 . You can also follow on that link

Answer 30

Ok

Answer 31

@MERTICH Did they help??

Answer 32

That's not the way to show the function for A. But no matter; we have enough information to answer the question.

(i) List the start values.

(ii) Identify the growth rates. We don't have to find a function for B and as it is decreasing we can dismiss it for the question.

(iii) Choose a starting value and growth rate to suit D. It looks like many answers are possible.

Bob

edit. I think this is really just a question about functions and graphs. The 'stock rates' is just window dressing.

22<Dstartprice<25, and it's difficult to figure out the growth rate for B, though I can tell that stock fell by 44c, then 43c, may be 42, 42......

IT WAS HARD ON US , SORRY DEAR.....

Re: I Ca'nt Figure Out If This Is An Exponential Question
You can forget about B as it's growth rate is negative. D has to have the second highest so it must be between A and C.

It could be exponential but no need to involve 'e'. Once you've chosen a rate you can write the function as a power function.

Re: I Ca'nt Figure Out If This Is An Exponential Question
Thank you guys! I really appreciate

Answer 33

I don't get it

Answer 34

YA, they failed to get the head and tail, as the function of stock D lies between 22 and 25, so it can be any number

Answer 35

I am so sorry that we could not help you. I couldn't keep my promise.

Answer 36

So it could be 21, 22, 23, or 24??

Answer 37

no, 22 is the lowest, the price for stock B, however, the price for stock D should be the second lowest, and since the start price for stock C is 25, then the start price for stock D shoould be between 22 and 25, 22<x<25

Answer 38

So it can be 23 or 24??

Answer 39

yes, 24.1 24.2, 24.5676, can be anything between the two

Answer 40

Ok and what about the others??

Answer 41

I'll make a new one

Answer 42

uhmmmm @Baseballa101 , i really hate lying to you. I think the problem above is now beyond my scope. Again, sorry for letting you down.

Answer 43

Thank you for trying and doing as much as you could @MERTICH

Answer 44

I tried dear, but none of my friends and mentors can help. But always mention me in other of your problems, will be there tot try and help again...
