What am I supposed to do?

5. anonymous

I do not understand..

6. campbell_st

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

7. anonymous

Is is 25?

8. campbell_st

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 ?

9. anonymous

Stock B 4% ?

10. campbell_st

great so the function is $f(x) =25\times(1.04)^x$ does that make sense

11. anonymous

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

12. anonymous

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

13. campbell_st

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

14. anonymous

Got that! Thank you!

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

16. anonymous

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

17. campbell_st

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

18. campbell_st

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

Not understanding what you mean..

20. anonymous

Nevermind I get what you're saying lol

Still need helpppp
