Suppose \( A \) is an invertible \( n \times n \) matrix and \( \mathbf{v} \) is an eigenvector of \( A \) with associated eigenvalue \(-6\). Convince yourself that \( \mathbf{v} \) is an eigenvector of the following matrices, and find the associated eigenvalues:

1. \( A^2 \), eigenvalue = \(\_\_\_\_\)
2. \( A^{-1} \), eigenvalue = \(\_\_\_\_\)
3. \( A + 5I_n \), eigenvalue = \(\_\_\_\_\)
4. \( 4A \), eigenvalue = \(\_\_\_\_\)
