    Curve Fitting

    Determine the coefficients of a polynomial of third degree that best fit the
    points:

    Code:
    X | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
    Y | -12 | -11 | -9 | -2 | 2  | 6  | 9 | 11 | 12 |
    I found this polynomial:
    P(x) = 0 -97,6x + 40,471x^2 -3,65x^3

    Are correct ?
