Question

michele_laino · Answer

please your starting prices are:
A. =25,
B=22,
C=30
so I think you have pick a starting price less than 25, are you agree?

lacedupcountry · Answer

Ohh okay, yeah i agree i totally messed that up @Michele_Laino sorry i didn't get back sooner i was taking another test so i could do 23?

lacedupcountry · Answer

So i changed question 1:
F(x)=23(1.3)x

swagster23780 · Answer

I agree with Michele_Laino

lacedupcountry · Answer

Yes and i did that, I got rid of all of my other answers and made a new Function. Now can someone help me out the rest of the way please? With number 2?

lacedupcountry · Answer

2.	Graph the price function for Stock D. Explain the key features of the graph with complete sentences.
so would i write it like this:
F(1)=23(1.3)1
F(1)=29.9
F(2)=23(1.3)2
F(2)=59.8
F(x)=59.8x

for $\large\tt \color{red}{A}$


$$\large f(x)=25(1.08)^x$$

$\large\tt \color{black}{A~~initial ~~value =25}$


it is equal to $\Large\tt \color{blacck}{increase}$ in for $\Large\tt \color{blacck}{8\%}$ per day

for $\large\tt \color{red}{B}$

$\large\tt \color{black}{B~~initial ~~value =22}$


$\large\tt \color{black}{21.56=22(0.98)
         =22(1-0.02)}$


hence for B it will be $\Large\tt \color{blacck}{decrease}$ in $\Large\tt \color{blacck}{2\%}$ per day


for $\large\tt \color{red}{C}$

it is already given 


$\large\tt \color{black}{C~~initial ~~value =30}$


it is equal to $\Large\tt \color{blacck}{increase}$ in for $\Large\tt \color{blacck}{4\%}$ per day

for$\large\tt \color{red}{D}$

second lowest starting price=$\large\tt \color{black}{25}$


second highest rate of growth=$\large\tt \color{black}{4\%}$


there for function for D will be


$\Large\tt \color{black}{f(x)=25(1.04)^x}$


x          f(x)

0          24

1          26

2          27.04
