Solve the following problem.

1 1 4 Problem 3(*): Consider the system A5: = E where A = 2 1 and E: D . 1 1 2 a Show that the system is inconsistent. 15 o Suppose that 55* = [:i] is the least squares solution to the system An": = 5. Explain 2 in a complete sentence what that means. Be clear and concise (20 words or less). a Set up the equations needed to nd :i:*. up Use the equations above to nd all least squares solutions 5." to AE = b. . Compute projim(A)(b), the orthogonal projection of b onto Im( A). . Compute the minimum value of E(x) = | |Ar - bl| over all T E R2
