You can put this solution on YOUR website!
1) y=-|x-3|
Plot a few points around x=3
If x=3, y=0
If x=2, y=-1
if x=1, y=-2
If x=4, y=-1
If x=5, y=-2
-----------------

---------------------
3) y=2|x+2|-3
Plot a few points around x=-2
If x=-2, y = -3
If x=-3, y = -1
If x=-4, y = 1
If x=-1, y = -1
If x=0, y = 1
Plot those points and you will see the shape of the graph
