Linear transformation matrix problem

[snoggerT]

let A= $$\left( \begin{array}{Ccc} 9 & 0 \\ 2 & 6 \\ \end{array} \right)$$
and B= $$\left( \begin{array}{Ccc} 5 & 1 \\ 3 & 4 \\ \end{array} \right)$$

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

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.
