Answer 3

What am I supposed to do?

Answer 4

I do not understand..

Answer 5

ok... for the starting price x = 0

so for stock A what is the starting price, substitute x = 0

Stock B read the table and find the value of f(x) when x = 0

Stock C it says that the starting price is $30...

identify the middle value of the 3

thats step 1

Answer 6

Is is 25?

Answer 7

correct

now for the rate of growth

Stock A has 1.08 this represents a 8% increase

Stock B as a 4% growth rate

Stock C the price seems to be falling.

so which is the middle ?

Answer 8

Stock B 4% ?

Answer 9

great so the function is

\[f(x) =25\times(1.04)^x\]

does that make sense

Answer 10

Yes, I understand this part now! Yet, I'm not sure how I would word it to justify that answer either..

Answer 11

I would just explain how I found the numbers to input?

Answer 12

of... for the starting price use x = 0... in for each stock... that is the initial value...

so say something like, find the value when x = 0... then give the 3 values

as for the rate of increase...

the 1st model is 1.08 so the rate of increase is 8%

and then for B the price is declining you are told C = 4%

so talk about those things

Answer 13

Got that! Thank you!

Answer 14

Now, how would I graph this? What kind of graph...

Answer 15

What does it mean by "key features?" @campbell_st

Answer 16

use this site to graph it

it will do it easily.... just enter it as

y = 25*(1.04)^x

https://www.desmos.com/calculator

Answer 17

well the graph is only 1st quadrant... show the initial price... the y- intercept...

and probably aboter 10 to 15 days the value may get a little silly

Answer 18

Not understanding what you mean..

Answer 19

Nevermind I get what you're saying lol

Answer 20

Still need helpppp
