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 - 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.
