Question 16 refers to the following figure.

Begin skippable figure description.The figure presents a graph of two curves in the xy-plane. The horizontal axis is labeledx, and the vertical axis is labeledy. There are evenly spaced horizontal and vertical gridlines along the axes. The first vertical gridline to the right of the yaxis is one unit from the yaxis, and the second horizontal gridline above the xaxis is 2units from the xaxis.
