Answer 1

\[y=\left| 3x-1 \right|\].

Answer 3

just examine wolframalpha output :D

Answer 4

I wonder why the link got messed up - trying again:

http://www.wolframalpha.com/input/?i=y%3D |3x-1|

Answer 5

All the sites and everything are telling me that it should be moved 1/3 of a unit to the right. And I dont know why. I never remember learning that, according to what i remember, it should be moved one unit to the right.

Answer 9

okay we have established that link is not going to work.

Answer 10

just copy/paste the link :)

Answer 11

Yeah, I went to the site, but it doesn't explain WHY. I am doing test corrections and must know why.

Answer 12

what do you mean by "moved one unit to the right" ?

Answer 13

The absolute value function is moved one unit to the right after it is graphed.

Answer 14

I believe it is moved down one unit and expanded by 3

Answer 15

you see its x is not equal to 0 when the graph starts to go the way up :D

Answer 16

The "-1" causes it to be shifted one unit vertically

Answer 17

I don't think it gives it a vertical shift. If it were y=|3x|-1 that would give it a vertical shift.

Answer 18

but since the graph is streched vertically X 3 , the horizontal movement as a result of the "-1" is only one third

Answer 19

Ohh, okay, thanks :D That's what I needed.

Answer 20
