FIT command syntax

Mth 163

I got all of the Derive worksheet done except for the last page. Everytime that I would try to enter the equations on the last page (such as y=ax^3), it would say that there were too many variables to plot. I am unsure of what I am doing wrong. Please let me know.

You have to use the syntax of the FIT command as instructed prior to that point.

To fit y = a x^2, you would use

FIT([x, a x^3], ##),

where ## is the line number of your data set.
