In order to do a least squares approximation we will nedd to set a system of equations and then convert it to matrix form
Thus, using the given points
Thus, the system in Ax = b terms gives
The least squares solution is of the form
ATAx = ATb
====>
Thus
using the inverse of the matrix on the left on both sides with left multiplication we obtain
Thus,
