How to graph x=|y|?

OpenStudy (anonymous):

so there are no negative values of y. the bottom left quadrant is translated into the top

OpenStudy (anonymous):

mirrored sorry

OpenStudy (anonymous):

so is this the same exact graph as y=|x|?

OpenStudy (anonymous):

|dw:1351030143245:dw|

OpenStudy (anonymous):

thats y = absolute value of x since x can never be negative

OpenStudy (anonymous):

just bounces back from the origin

OpenStudy (anonymous):

what he said! :D

OpenStudy (anonymous):

:P

OpenStudy (anonymous):

wait isnt that backwards?

OpenStudy (anonymous):

|dw:1351030250941:dw|

OpenStudy (anonymous):

whichever term has absolute value can only ever be in a positive area

OpenStudy (anonymous):

oh. so x=|y| is the sideways one?

OpenStudy (anonymous):

no, absolute value of y means the graph can never go into the bottom. the bottom half is negative for y. y can never be negative

OpenStudy (anonymous):

y can be negative cant it? if you try to make a table of points, then its just that x can never be negative isnt it

OpenStudy (anonymous):

no if you have stated $\left| y \right|$ then you are saying "y can never be negative"

OpenStudy (anonymous):

$\left| x \right|$ x can never be negative

OpenStudy (anonymous):

$\left| cupcake \right|$ cupcake can never be negative

OpenStudy (anonymous):

$hippo = \left| cupcake \right|$ |dw:1351030947140:dw|

OpenStudy (anonymous):

i still dont get it

OpenStudy (anonymous):

|dw:1351031130407:dw|

OpenStudy (anonymous):

you got that?

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

|dw:1351031188363:dw|

OpenStudy (anonymous):

okay so what do you want to do. x = absolute value of y, or y = absolute value of x?

OpenStudy (anonymous):

x= abs val of y

OpenStudy (anonymous):

okay so what is y when x is 1?

OpenStudy (anonymous):

1

OpenStudy (anonymous):

cool, and when x is 2 y is 2, x is 3 y is 3, x is giraffe y is giraffe. okay what is y when x is -1
