# Math Help - Set Points

1. ## 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 ?
