Answer 1

Where's the problem?

Answer 2

Hi, let me post the question @Idealist

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.

Answer 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 5

You think you can help?

Answer 6

a) f(x+2)---> It's shifting to the left
b) f(-x)--->reflecting
c) f(x)+3---> It's shifting up by 3

That's all I know. Sorry that I couldn't fully help you.

Answer 7

Hmm, thanks anyway!

Answer 8

YW!

Answer 9

If you could, do you think you could help me how to graph?

Answer 10

@Hero please help

Answer 11

Okay...

Answer 12

Hi can you help on my Function?

Answer 13

I know this...
a) f(x+2)---> It's shifting to the left
b) f(-x)--->reflecting
c) f(x)+3---> It's shifting up by 3

Answer 15

Try to understand what is happening

Answer 16

Thank you! But could you also tell me what to do with the data!

Answer 17

Do I simply show the graph? I also need the changes in sentences!

Answer 18

@Hero I dont need the answer, just help me get it :)

Answer 19

Here's a better graph

Answer 20

You describe each change in terms of f(x)

Answer 21

But why does the data change like that?

Answer 22

It hasn't changed. The only thing that has happened is that I manipulated the window settings so that you can see the graphs better.

Answer 23

No I mean what does the data show?

Answer 24

The red graph is price?

Answer 25

The red graph represents f(x).
When the red graph is flipped over the y axis, it becomes the green graph or f(-x).
When the red graph is shifted two units west, it becomes the blue graph of
f(x + 2).
When the red graph is shifted three units north, it becomes the purple graph or f(x) + 3.

Answer 26

Yes, the red graph is f(x)

Answer 27

Ok so umm... thank you bud, hope to see you around soon! BYE!

Answer 28

You're welcome.
