\left(\right)\vec c=\left(\right)
Solve
(4, -11/10)
Now let's fit a quadratic function.
\left(\right)\vec c=\left(\right)
[ 4 10 30]
[ 10 30 100]
[ 30 100 354]
(11/4, 3/20, -1/4)
And finally a cubic. We expect the cubic to exactly go through the points since there are 4 points and a cubic has 4 constants to pick.
\left(\right)\vec c=\left(\right)
[ 4 10 30 100]
[ 10 30 100 354]
[ 30 100 354 1300]
[ 100 354 1300 4890]
(15, -58/3, 17/2, -7/6)
