Question

I really need help!

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 B C
Price
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 2

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.
choose a number between 25 and 30 please.

Answer 3

27

Answer 4

now pick a number between 1.08 and 1.4

Answer 5

1.3

Answer 6

here this is easier to explain and shorter 26 and then 1.3

Answer 7

f(x) = 26(1.3)x
that is your equation.

Answer 8

Number one was the easy part.

Answer 9

f(x) = 27(1.3)x right?

Answer 10

yeah

Answer 11

2.) Graph the price function for Stock D. Explain the key features of the graph with complete sentences.
to do this we would need to solve the equation and graph it do u know how to do this?

Answer 12

sorry my internet is slow ok hold on let me do this

Answer 13

its ok

Answer 14

I don't think you can open this file but its worth a try

Answer 15

I couldn't but i know what it is so lets skip this step.

Answer 16

its geogebra and ok

Answer 17

f(1) = 26(1.3)1
f(1) = 33.8?
f(2) = 26(1.3)2
f(2) = 67.6
=
f(x) = 33.8x

Answer 18

so all you need to do is fill in the numbers you have with these

Answer 19

the x is the days and the y is the amount

Answer 20

wait what?

Answer 21

never-mind that

Answer 22

do you understand the equation?

Answer 23

and how I got the answer

Answer 24

is it a sequence

Answer 25

yes

Answer 26

ok for 3

Answer 27

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).
for this you would just do this.
1 + -6
2 + -6
3 + -6

Answer 28

So if im going to submit it how should I write it

Answer 29

just like that but with the numbers you chose.

Answer 30

do put the f(x) and the eqaton then etc?

Answer 31

yes

Answer 32

ok are you ready for number 3?

Answer 33

yup

Answer 34

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).
for this you would just do this.
1 + -6
2 + -6
3 + -6

Answer 35

since g(x) = -6 and we were graphing it per day so the first day would be 1 + -6 the second day would be 2 + -6 and the third day would be 3 + -6


If you needed farther explanation.

Answer 36

so I just put that?

Answer 37

yes/are you graphing this?

Answer 38

yes so what exactly is the equation to graph?

Answer 39

f(x) + g(x)
so
f(x) + -6.

Answer 40

f(x) = 26(1.3)x

Answer 41

you get it?

Answer 42

um I just got confused lol

Answer 43

haha

Answer 44

lol

Answer 45

you will graph f(x) + -6.

Answer 46

ready for number 4?

Answer 47

wait not yet i have just a question

Answer 48

F(1) + g(-6) = 33.8 - 6?
F(1) + g(-6) = 27.8?

my bad haha

Answer 49

what is your question?

Answer 50

So for number three what equation am i supposed to graph and what exacly am i supposed to put im like 99.99% lost

Answer 51

lol

Answer 52

haha

Answer 53

f(1) = 26(1.3)1
f(1) = 33.8?
f(2) = 26(1.3)2
f(2) = 67.6
=
f(x) = 33.8x



you see where i put my explanation numbers

Answer 54

so i just put that when im answering the question

Answer 55

if you are using my numbers yes

Answer 56

if not impute your numbers where mine are

Answer 57

then what do i graph

Answer 58

F(1) + g(-6) = 33.8 - 6
F(1) + g(-6) = 27.8

Answer 59

both?

Answer 60

both

Answer 61

or are you only supposed to graph 1 equation?

Answer 62

i have no idea but ill graph both

Answer 63

haha ok

Answer 64

ready for number 4?

Answer 65

yes but just to make sure i put that and graph te two equations?

Answer 66

yes

Answer 67

ok so on to #4 right?

Answer 68

yeah

Answer 69

once you graph the new function, 4 is just nothing but "translations" or "transformations" or "shifts" of THAT graph

Answer 70

So i graph them all and say that?

Answer 71

once you have graph for f(x)+g(x), or the new function, the lines in 4 just shift it or move it about

Answer 72

wait what?

Answer 73

so what is the new function?

Answer 74

have you covered "functions translations or transformations" yet?
or function shifts

Answer 75

im on graphing exponential equations

Answer 76

so have you covered it?

Answer 77

kind of but i really don't get it

Answer 78

ok so the functions gets moved about, and that movement, is reflected in the function values PADDING it

Answer 79

oh ok

Answer 80

so is that what i ps for each?

Answer 81

?

Answer 82

sorry bad wifi

Answer 83

yes, (4) is just transformations or shifts of the function you'd graph in (3)

Answer 84

lol i feel u my wifi is so laggy today

Answer 85

haha

Answer 86

thats the answer

Answer 87

wait so i would turn this in like this?

Answer 88

?

Answer 89

can you see it?

Answer 90

hello?

Answer 91

@mjoxprm360 please check

Answer 92

@mjoxprm360 ?

Answer 93

im sorry my computer crashed

Answer 94

yes it looks great

Answer 95

lol tht sucks and thatnks what do I put on the bottom tho

Answer 96
