Justify each answer T(x₁x₂x3)(x-5x₂ + 2xy.x₂ - 7x₂) (a) is the linear transformation one-to-one? OA. T is one-to-one because T(x)=0 has only the trivial solution OB. Tis one-to-one because the column vectors are not scalar multiples of each other. C. T is not one-to-one because the columns of the standard matrix A are linearly independent COD. Tis not one-to-one because the columns of the standard matrix A are linearly dependent. (b) is the linear transformation onto? OA. T is not onto because the standard matrix A does not have a pivot position for every row B. Tis onto because the columns of the standard matrix A span R² > OCT is not anto because the columns of the standard matrix A span R OD. Tis onto because the standard matrix A does not have a pivot position for every row Khaled Mardini This test: 100 point( possible This question: 8 point(s) possible Time Remaining: 00 43:26 Copyright © 2022 Pearson Education Inc.
