Linear mappings: Linear mappings
Finding the matrix that determines a linear mapping
The linear map \(A \) from \( \mathbb{R}^2 \) into \(\mathbb R^2\) satisfies
\[\begin{aligned}
A\cv{-1\\-2} &= \cv{3\\-7}\\
A\cv{3\\1} &= \cv{-9\\16}\tiny{.}
\end{aligned}\]Determine the matrix of \( A\) with respect to the unit vectors.
