2 in the set generated by Is {} Explain why the question "Is in the set y{B1...Bwhere all the vectors are columns of the same height) is really just asking for the solution of a certain linear system. Problem B Which of the following are singular? 12 1 3 2 1 -3 -6 12 1 1 3 1 1 2 1 1 3 1 3 4 7 2 1 2 1 0 5 1 1 4 Problem C List all of the reduced echelon forms possible for the following size matrices. Use an asterisk for entries which can be anything. Explain briefly how you know you have them all. 2x2 2x3 3x2 3x3
