Use the fill handle to create your data range by a set increment for each data value. The value of each cell will be shown in a ScreenTip as you drag through the cells.
Because this is just an exercise to see how the shape of the curve changes, you can create your own data. Using an initial data point, keep adding a set increment to get enough data to plot a good curve for a single set of parameter values.
In this case you'll need about 50 data points to create a smooth curve.
