The transformation S is represented by the matrix \(\left[ \begin{array} { l l } 3 & 0
0 & 1 \end{array} \right]\)
The transformation T is a translation by the vector \(\left[ \begin{array} { c } 0
- 5 \end{array} \right]\)
Kamla transforms the graphs of various functions by applying first S , then T .
Leo says that, for some graphs, Kamla would get a different result if she applied first \(T\), then \(S\). Kamla disagrees.
