Let r(x) = [x] - 1 for every real number x. Describe how to obtain the graph of y = r(x) from the graph of y = p(x). Sketch the graph of y =r(x) on the same set of axes as the graphs of y = p(x) and y = q(x).​

Choose the domain & range of the relation shown in the graph: domain: -1, 0, 1, 2, 3 range: -3, -1, 0, 3 domain: -3, -1, 0, 3 range: -3, -1, 0, 3 domain: -3, -1, 0, 3 range: -1, 0, 1, 2, 3 domain: 3, 1, 0, 3 range: -1, 0, 1, 2, 3
