Fitpoly in arithmetic

Needs Answer


I use fitpoly when drawing graphs passing through a set of data points, but I am now in position where I need to estimate curves by hand..

So can I ask what arithmetic method that Geogebra uses in fitpoly?

I found some methods like newton interpolation but I am still not sure it is the same thing as Geogebra uses.

Can you make a sample (if possible as ggb-file) and explain a little bit more.
