Piecewise help

How to determine range and how to know which direction the line is pointed on the graph
@Helpmeplz123, You seem to have a completely distorted view as to how this forum works.
You post the exact wording of a question with which you have issues.
Then you post whatever you have been able to do towards its solution.
At that point, ask for help with the question.
 
I remember the good ole days when helpers on this forum liked a real challenge!
But I do admit that this post is stretching it a bit.
