Imagine the graph of y=|x-1|. Now shift it down 2 units, then reflect all parts of the curve below the x-axis in the x-axis.
Using this new reflected graph, shift it down by 3 units, then reflect all parts of this new curve below the x-axis in the x-axis.
Using this new reflected graph, shift it down by 4 units, then reflect all parts of this new curve below the x-axis in the x-axis.
Using this new reflected graph, shift it down by 5 units, then reflect all parts of this new curve below the x-axis in the x-axis.
Using this new reflected graph, shift it down by 1 units, then reflect all parts of this new curve below the x-axis in the x-axis.
Using this new reflected graph, shift it down by 2 units, then reflect all parts of this new curve below the x-axis in the x-axis.
