here is $y=|x-2|$ free hand |dw:1358093601371:dw|

anonymous · Answer

if you want $y=-|x-2|$ flip it over the $x$- axis

in terms of h a's and k's?

anonymous · Answer

i have no idea what h's and k's are
$y=|x|$ looks like a V sitting right at the origin $(0,0)$
$y=|x-2|$ looks like that same V  moved to the right 2 units
$y=-|x-2|$ looks like that same V upside down, because of the minus sign out front  (whatever was up is now down)

anonymous · Answer

so 
$$y=a|x+h|+k$$
a positive h moves the v graph to the right, and negative h to the left
how does the value of "a" effect the graph? does it make it upside down if it's negative?

anonymous · Answer

I guess I wrote that wrong, if h is positive the graph goes to the left and vice versa
