Hi!

I am currently working on this question about matrices and showing they are homomorphisms. I have done part (i), but on part (ii) I am confused as the matrix is mapping to a - I have never seen this before and I'm not sure how to approach it. I know that usually you would work out the determinant and show that det(AB)=det(A)det(B), but I can't figure out how this would be different.

Thanks in advance!
