You should be able to Fnd a basis for the kernel and image of a linear transformation, and determine its dimensions. 5. What are the eigenvectors and eigenvalues of a matrix? 6. What does it mean to diagonalize a matrix? 7. ±ind an example of a matrix that is not diagonalizable. 8. How are linear transformations and matrices related? 9. You should understand the connection between the kernel and image of a linear transformation, its rank, the existence of an inverse, the concepts of injectivity and surjectivity, and the existence of solutions to a linear system of equations. 10. Why are eigenvalues and eigenvectors important? How can you recon-
