Question: Let A = [2 1] ws color 2 = 3 2 3 and b - -61 H -6 The QR factorization of the matrix

Let A = [2 1] ws color 2 = 3 2 3

Let A = [2 1] ws color 2 = 3 2 3 and b - -61 H -6 The QR factorization of the matrix A is given by: -2] 3 3- 0 -/2 5 3 2 3 (a) Applying the QR factorization to solving the least squares problem Ax = b gives the system: :+8 X = 2 3 (b) Use backsubstitution to solve the system in part (a) and find the least squares solution. 48 -18
