For question (a) I can solve it by taking matrix A and multiplying it with each vector of bases B to find [T(vi)]_B'.
However, I'm confused on how to find T(v1) and so on.
What I tried was taking the values I had from part (a) and putting them in columns to make a 3x4 matrix. Then I multiplied that matrix with the vectors in basis B. I feel like this is wrong and I need clarification and proper guidance to do this problem.
Can someone help me please?
Thanks
