FitPoly( <List of Points>, <Degree of Polynomial> )
Calculates the regression polynomial of degree n.
Example: FitPoly({(-1, -1), (0, 1), (1, 1), (2, 5)}, 3) yields f(x) = x3 - 1 x2 + 1.


CAS Syntax

FitPoly( <List of Points>, <Degree of Polynomial> )
Calculates the regression polynomial of degree n.
Example: FitPoly({(-1, -1), (0, 1), (1, 1), (2, 5)}, 3) yields x3 - x2 + 1.
