Question

Algebra 1 question! please help!

Will post graph in a bit

Answer 1

stock A B C
Price f(x) = 25(1.08)x x f(x) The initial price of this stock is $30, but it has
0 22.00 been increasing 4% each day
1 21.56
2 21.13

Answer 2

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 3

flvs algebra 1?

Answer 4

stock A B C
Price f(x) = 25(1.08)x x f(x) The initial price of this stock is $30,
0 22.00 but it has been increasing 4% each day
1 21.56
2 21.13

Answer 5

yep

Answer 9

i think i have an answer for the first part

Answer 10

@Hero

Answer 11

ok

Answer 12

do you still need help?

Answer 13

yes i do :)

Answer 14

alright so...

Answer 15

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 16

i need help with the last 2 parts

Answer 17

wait do you need help on the first post?

Answer 18

you mean this post?

Answer 19

oh sorry ok

Answer 20

what was the function you created

Answer 21

which means it started at 23 dollars and has a growth rate of 5% right?

Answer 22

thats right

Answer 23

"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)."

Answer 24

this means f(x)+g(x) OR 23(1.05)^x-6

Answer 25

ahh i see...

Answer 26

Are you familiar which the graphing software GeoGebra?

Answer 27

not really, i can look it up and figure it out

Answer 28

https://www.geogebra.org/

Answer 29

downloading it now

Answer 30

press start creating and you need to log in with your google account

Answer 31

ok

Answer 32

Once it finishes downloading, you need to input the function 23(1.05)^x-6

Answer 33

i added it to chrome now what?

Answer 34

essentially your graph should look something like this

Answer 35

i see

Answer 36

so in your solution for "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)." you can write....

f(x)+g(x) = 23(1.05)^x-6
(and post the graph under it)

Answer 37

i understand, now whats next?

Answer 38

For the last question...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.

Answer 39

this is basically just substituting

Answer 40

f(x) stands for the function of x

Answer 41

the exponent (^x) that you see at the end of your function is the same thing

Answer 42

For example, your first one is f(x+2) right?

Answer 43

right

Answer 44

By substituting, your new function would be f(x+2)23(1.05)^(x+2)

Answer 45

are you familiar which
f(1)23(1.05)^1
f(2)23(1.05)^2
f(3)23(1.05)^3
f(4)23(1.05)^4

Answer 46

these are the same things

Answer 47

ok so just plugging in the x values

Answer 48

Yes!

Answer 49

f(x+2)=23(1.05)^(x+2)
f(-x)=23(1.05)^(-x)
f(x)+3=23(1.05)^x+3

Answer 50

these would essentially be your substituted functions

Answer 51

you just need to put them into a graphing software and apply all of them on one graph

Answer 52

sorry my computer froze

Answer 53

It's ok

Answer 54

this picture is the graph for all your functions

Answer 55

y = f(x) where y is the dependent variable and x is the independent variable. This means when the independent variables changes, the dependent variable also changes. The function can shift and the money he is investing will either drop or increase. For example, f(x) + 3 means that the y-intercept will go up by three and Gordon’s stock will increase.

Answer 56

Do you understand? any questions I can answer?

Answer 57

i dont know how to graph them...

Answer 58

oops take away the f(x+2) from the function, remember it is already inserted at the end of the function, like instead of f(x+2)=23(1.05)^(x+2), put in 23(1.05)^(x+2)

Answer 59

ok i did it and my graph is still blank

Answer 60

want me to take a picture?

Answer 61

sure

Answer 62

The manage bar is on stop of GeoGebra, the last icon looks like a compass rose

Answer 63

press on it and press "move graph views"

Answer 64

This way you can drag the graph, by dragging it to the bottom right a little bit, you should see your results

Answer 65

23(1.3)^(x+2)
23(1.3)^(-x)
23(1.3)^x+3

Answer 66

Put all these in on the same graph and it is the solution

Answer 67

ohh ok thanks man!

Answer 68

to explain the last question, y = f(x) where y is the dependent variable and x is the independent variable. This means when the independent variables changes, the dependent variable also changes. The function can shift and the money he is investing will either drop or increase. For example, f(x) + 3 means that the y-intercept will go up by three and Gordon’s stock will increase.

Answer 69

So he can lose or gain money depending on the function xD

Answer 70

lol ok, thanks man really appreciate all the help! gave you a medal and fan

Answer 71

Alright you're welcome, peace!

Answer 72

peace :)
