Find an approximating polynom of known degree for a given data.
 
===Example===
For input data:
x = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
y = {1, 6, 17, 34, 57, 86, 121, 162, 209, 262, 321};
The approximattingapproximating polynom is:
3 x<sup>2</sup> + 2 x + 1
2
Here, the polynom's coefficients are (3, 2, 1).
3 x + 2 x + 1
Here, polynom's coefficients are (3, 2, 1).
