#### Solution Preview

This equation is of the form AX = L X

where L is the eigen value corresponds to the matrix A with respect to the characteristic matrix X

And this corresponds to a linear transformation. ...

#### Solution Summary

This shows how to explain why a transformation is not linear or write the matrix that represents the transformation.
