First, are you really familiar with the graph of y = [x]? If so, your answer choices move that graph up or down.
A. Move the graph of y=[x] UP 3 units B. Move the graph UP 1 unit C. Move the graph DOWN 1 unit D. Move the graph DOWN 3 units
The graph you're given on the problem screen is not a very good one, I think. Would it help to draw y = [x] on a piece of graph paper where one square = 1 unit? The graph you're shown has one square = 2 units, which could lead to some confusion.
So, draw the graph of y = [x], then figure out which way the graph was moved -- and how far -- to get the graph in the problem.
