yessir

Answer 3

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 f(x) = 25(1.08)x
x f(x)
0 22.00
1 21.56
2 21.13 The initial price of this stock is $30, but it has been increasing 4% each day.
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.
Graph the price function for Stock D. Explain the key features of the graph with complete sentences.
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).
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 4

ill post the question part neatly
one sec

Answer 5

a screenshot would be better since you don't have to worry about weird format issues

Answer 6

oh okay one sec

Answer 7

thanks

Answer 8

stock B is blank. Is that a typo?

Answer 9

my appologies

Answer 10

ah I see now

Answer 11

so you can completely make up the equation for stock D as long as it fits those conditions

Answer 12

you first need to find the starting price for each stock

do you know how to do this?

Answer 13

:/ not really man im trying to get this out of the way because im so far behind :(

Answer 14

plug x = 0 into the f(x) function

what result pops out?

Answer 15

f(0) = 25(1.08)0??

Answer 16

more like 25*(1.08)^0

Answer 17

use a calculator to compute 25*(1.08)^0

Answer 18

25?

Answer 19

good

Answer 20

stock A's starting price is $25

Answer 21

stock B
in the table, when x = 0, what is f(x) ?

Answer 22

22
i believe lol

Answer 23

yes

Answer 24

C says the initial price is $30

Answer 25

Initial prices

A: $25
B: $22
C: $30
D: not yet determined

Answer 26

what is one possible price for D?

Answer 27

um i dont know 28 maybe

Answer 28

D has the second lowest starting price

Answer 29

wait what

Answer 30

oh 21.56??

Answer 31

sure, anything between 22 and 25

Answer 32

oh anything?

Answer 33

22 is the lowest, so pick anything between 22 and 25 to squeeze in D so it is the second lowest

Answer 34

o ok 23 sorry lol

Answer 35

and hey i reallly appreciate your help btw :)

Answer 36

np

Answer 37

yeah 23 works too

Answer 38

Initial prices

A: $25
B: $22
C: $30
D: $23

Answer 39

now you need the growth rate of each stock A through C

Answer 40

um

Answer 41

i know c has a growth rate of 4% each day but not the others

Answer 42

stock A has a growth rate of 8%

since 1.08 = 1+0.08

and 0.08 = 8%

Answer 43

okay but how do i find b is it inbetween 4 and 8 because i know D is going to have to be the second highest

Answer 44

is stock B growing or decaying

Answer 45

ahh i see, decaying my bad lol

Answer 46

solve for x

22*x = 21.56

x = ??

Answer 47

uh im stuck on that one lol

Answer 48

divide both sides by 22

Answer 49

divide both sides of what?

Answer 50

the equation

Answer 51

ohhh nvm duhhh jeses im dumb haha
