Never encountered these with |stuff| in it, not sure how to approach it? Sketch the following.....
the picture you have there is the graph of |x|.
for y = |x - 2|+1 you will shift that graph 1 unit up and 2 units to the right
is the second question |-x| or -|x|?
if it's |-x| it will be exactly the same as |x| the original graph.
if it's -|x|, you would just turn it upside down (that is, reflect it in the x-axis)
again, i'm just applying basic transformation rules, do you know them?
i would recommend drawing them point by point as topsquark says as well, jsut to get used to the concept of absolute value
