anonymous · Answer

I need to know also :)

;) thanks man! :D

@Chlorophyll

anonymous · Answer

A?

hero · Answer

@Firejay5, did you compute A yet?

anonymous · Answer

Could you help answer this?

anonymous · Answer

For me also. not just Fire :S

hero · Answer

y ≥ |x-1| -2 

Add 2 to both sides to get

y + 2 ≥ |x - 1|

Take the inverse absolute value of both sides to get

± (y + 2) ≥ x - 1

Add 1 to both sides to get
± (y + 2) + 1 ≥ x

anonymous · Answer

How would you graph it though?

hero · Answer

If you have to graph it, just leave it in the form given to you and use a  graphing calculator to graph it

anonymous · Answer

Ughh, ok.

anonymous · Answer

1. Graph y = x
2.  Shift the graph to the right 1 unit
3. Take only the positive segment,  then take the negative  segment make symmetry over x axis
4. Shift the whole graph down 2 units

anonymous · Answer

@Firejay5 does it answer your post, too?

firejay5 · Answer

yea I guess

hero · Answer

Actually, if he followed your steps precisely @chlorophyll, he would not have the right graph. There are a couple of mistakes with them.

hero · Answer

For example, if he graphed y = x, he would have

|dw:1347503678508:dw|

to begin with. But let's assume he already knows to start with 
|dw:1347503738442:dw|

Well, then you tell him to move it over one, then flip it over the x axis. If he did that, he would end up with

|dw:1347503826640:dw|

anonymous · Answer

Your graph is wrong, because when you shift the down, the graph is still in V shape :(

hero · Answer

I know it is wrong. I was following YOUR steps. Don't you understand?

anonymous · Answer

NO, I don't think my graph wrong! Could you show me why???

hero · Answer

I already attempted to show you.

anonymous · Answer

Then show the CORRECT one :P

hero · Answer

I don't want to post the answer on here

hero · Answer

I know what it should look like however.

hero · Answer

I was just saying that he would not get the right answer using your provided steps.

hero · Answer

It was a good attempt though

anonymous · Answer

It's up to you! I just try to help the poster. I'm still thinking about the how to explain the region, as the matter of fact  I'm not articulate type as you are :)

hero · Answer

I think it would be easier if you started by attempting to explain what y = |x| means and what it looks like, and then going from there.

anonymous · Answer

I don't think he has problem graphing y = x!

anonymous · Answer

When he's online, he'll surely ask more though!
