Linear transformation matrix problem

Click For Summary
SUMMARY

The discussion focuses on finding the matrix C of the linear transformation T(x) = B(A(x)), where A = [[9, 0], [2, 6]] and B = [[5, 1], [3, 4]]. The key conclusion is that the composition of two linear transformations can be represented by the product of their corresponding matrices, specifically C = BA. This method simplifies the process of calculating the transformation by directly multiplying the matrices A and B.

let A= [tex]\left(<br /> \begin{array}{Ccc}<br /> 9 & 0 \\<br /> 2 & 6 \\<br /> \end{array}<br /> \right)[/tex]
and B= [tex]\left(<br /> \begin{array}{Ccc}<br /> 5 & 1 \\<br /> 3 & 4 \\<br /> \end{array}<br /> \right)[/tex]

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.
