The points used in plotting the graph of the absolute function as given are; (-2,3), (-1,2), (0,1), (1,0) and (2,1).
The absolute function given is; y = | x − 1 |
Hence, by consider x-values; -2,-1,0,1,2....it follows that the corresponding y-values which are all positive by virtue of the absolute value symbol are; 3, 2, 1, 0, 1.
Hence, the points are; (-2,3), (-1,2), (0,1), (1,0) and (2,1).
