Can you do f through h, but please do all the parts in the question?

2. Find all eigenvalues and a corresponding eigenvector for each matrix below without cal-
culations by thinking it out using the linear transformation's geometric interpretation.
Write a few words (like 5) in each case explaining why your eigenvector/eigenvalue pair
works. For each matrix, graph each eigenvector and it's image after the transformation as
well as a random NON-eigenvector. Check your graph is accurate by showing the matrix
multiplication.
