Put values of x you care about; say, lowest to highest, in increments of
(x_hi - x_low)/1000; one way to do this is by using Edit/Fill/Series
(put x_low in a cell, select it, go to the command, put in x_high as the
final point, specify columns, increment); you could also set up a series
of formulas that you copy down a column. Put your formula in the
adjacent column. Select both columns of data, click on the chart wizard
icon, select XY (Scatter) as your chart type, and go.
