A linear transformation is represented by the matrix A=(1224).A=\begin{pmatrix}1&2\\2&4\end{pmatrix}. A parallelogram is formed by the two vectors u⃗=(1,0)\vec u=(1,0) and v⃗=(0,1)\vec v=(0,1) placed tail-to-tail at the origin (so the parallelogram is the unit square). Which conclusion follows from the determinant value?
