You may use your graphing calculator now. If you use it for some task, like finding an RREF matrix, make a note that you did so. Let A = [1 0 0 8 5 2 -3 -4 0 3 2 2 1 1 -5 -3]. Can each vector in R^4 be written as a linear combination of the columns of the matrix A? Give a complete explanation, not just a "yes" or "no". Let T be the linear transformation whose standard matrix is [-3 -2 -1 1 3 -2 5 -2 -15 -6 -9 6 -4 1 6 -2]. Is T one-to-one? Is T onto? Answer each question by saying something specific about the pivots of A.
