Please help me with this question.

Please note: The last line of the question, which somehow got cut off, should be -7

Solution

If T: V W has the matrix representation T (X) = AX, where A is the given matrix, then by substituting (8,-7)^T for X, we get T ( (8,-7)^T ) = A (8,-7)^T = (-6,-29,103)^T.

Thus, the answer is (-6,-29,103)^T.

Note:

If the matrix representation (A) of the transformation T: V W is known, B_v and B_w are not needed to compute AX where X belongs to V = R².
