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

kk let me see old question...

undeadknight26 (undeadknight26):

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

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

3 years ago
OpenStudy (anonymous):

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

Js @undeadknight26 C is a stock

undeadknight26 (undeadknight26):

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.

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

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

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.....

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

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

undeadknight26 (undeadknight26):

there is our function for part D.

OpenStudy (anonymous):

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,

How do I find the start price though?

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.

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...... Report | Delete | Edit | Quote #13 Today 08:07:21 bob bundy IT WAS HARD ON US , SORRY DEAR..... Online 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.

I don't get it

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

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

3 years ago
OpenStudy (anonymous):

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

3 years ago
OpenStudy (anonymous):

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

So it can be 23 or 24??
