put a formula representing the equation in a sheet and refering to the cell
to the left
File the formula down for as many points as you want to graph

put x values in the adjacent cell.

Graph the two columns using an X-Y scatter plot

Excel graphs numbers, so one way or another you have to feed the graph
numbers.
