The goal of this problem is to fit a quadratic function of the form f(z) = c+ c₂² to the data points (-3, 76), (-2, 13), (1,4), (2, 21), using least squares. (a) The problem is equivalent to finding the least squares solution to the system Xc = y where X= .y= and c = [c₁, c₂]™ (b) Find the coefficients of the best fit by finding the least squares solution to the system in part (a) C1
