$$\mathbf { A } = \left( \begin{array} { r r }
2 & - 1
4 & 3
\end{array} \right) , \quad \mathbf { P } = \left( \begin{array} { r r }
3 & 6
11 & - 8
\end{array} \right)$$
- Find \(\mathbf { A } ^ { - 1 }\)
(2)
The transformation represented by the matrix \(\mathbf { B }\) followed by the transformation represented by the matrix \(\mathbf { A }\) is equivalent to the transformation represented by the matrix \(\mathbf { P }\). - Find \(\mathbf { B }\), giving your answer in its simplest form.
