Linear transformation problem

  1. Apr 1, 2008 #1
    let A= [tex]\left(
    9 & 0 \\
    2 & 6 \\
    and B= [tex]\left(
    5 & 1 \\
    3 & 4 \\

    Find the matrix C of the linear transformation T(x)=B(A(x)).

    3. The attempt at a solution

    - Once again, I really don't know how to start a problem like this off. I tried finding just T(x)=Ax and then multiply that by B, but that didn't seem to work. Please help.

    If A and B represent two linear transformations f and g with respect to a pair of bases, then g(f) is just BA.

    okay, I see that now. thanks.
