drop down box in the upper left. You can then manipulate the parameter *k* in one of three ways. You can drag
The point *A* on the graph up and down, you can drag the slider on the left left or right or you can type in the
value for *k* in the box above the slider. All of these manipulations are limited to k values within the Range
