T: R3 -> R3 is given by:

Determine the matrix representation A for the image of T.

Correct answer:

What do they mean "Determine the matrix representation A for the image of T"? How do they arrive at the matrix representation that they do? My first thought was to determine the matrix by setting its columns to T (ex), T (ey), T (ez), where e is the respective column in the identity matrix but this will not be the same as the answer given above
