# Math Help - Linear Transformation T-- HELP!!

1. ## Linear Transformation T-- HELP!!

the standard matrix
[T ] of a linear

transformation
T is given. Use it to find T (x).

T = (1 2
3 4)

x = (3
-2)

The parantheses are the best I could do to show the matrices.

2. $T(\vec x) =TX=\left(\begin{array}{cc}1&2\\3&4\end{array}\rig ht)\left(\begin{array}{c}3\\-2\end{array}\right)=...$ where $X$ is the coordinate matrix for $\vec x$.
