Suppose T:R4 R3 is the transformation induced by the following matrix A. Determine whether T is one-to-one and/or onto. If it is not one-to-one, show this by providing two vectors that have the same image under T. If T is not onto, show this by providing a vector in R3 that is not in the range of T. A = [0 -3 -9 -3; 0 2 6 2; 1 -2 -6 -6]
