For the first one, the range will be and not as written by the OP above (I can't quote it easily because it's inside another quote). Prove It's explanation is good, so try to break it down and understand Prove It's posts. For the second one, think of the range of |x-3| and then think how dividing that by 2 affects it ("hint": in this case it doesn't). For the last one, think about the range of |x-6| and then the range of |x-6| + 4, etc.
