System Dynamics

Use the polyfit function to find the first- and second-degree polynomials that fit the following data in the least-squares sense. Evaluate the quality of fit for each polynomial.

$\begin{array}{l|lllllllllll}x & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 \\\hline y & 48 & 49 & 52 & 63 & 76 & 98 & 136 & 150 & 195 & 236 & 260\end{array}$
