Question

In desperate need of help. Fan and Medal

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: 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 10

@Baseballa101 I tried to solve it but I couldn't figure it out. I'm sorry :(

Answer 11

Ok, thanks anyway

Answer 12

Uhmmm, a tricky one indeed. Ok, to answer question (a), the price function of stock D, given that price is increasing by 4% each day, I am not sure about anything here, but maybe we can come out with something, is that exponential rise in price, or it is 0.4% of $30? If it is 0.4% 0f $30 , then \[h(x) = 30 + (0.04 \times 30)x = 30+ 1.2x\]
where x is the number of days. And attached is the graph for the above function

Answer 13

But then, the words" rate of growth make me want to believe that this is exponential growth.

Answer 14

Idk, I've been stuck on this for a LONG time and everyone I ask can't figure it out, or I get different answers

Answer 15

@MERTICH where did you go??

Answer 16

checking out exponentials brb

Answer 17

OK, I believe it is a question on exponential.
\[y(t)=a \times e ^{kt}\]

Where y(t) = value at time "t"
a = value at the start
k = rate of growth (when >0) or decay (when <0)
t = time

Answer 18

so in our case it will be
\[y(x) = 30\times e ^{1.2x}\]

Answer 19

Is this still number 1??

Answer 20

@Jordannyah can you help?

Answer 21

ya, that is the first part. As I said, it's a question on rate of growth, it requires intense knowledge of exponentials.

Answer 22

I'm not really good at exponentials
