Determine if the statements below are true or false. Make sure to justify your answers! You will receive no credit for simply selecting "true" or "false", or providing little explanation. 4.1 True or False: If A is a 4 x 4 matrix with only one eigenvalue, then A is not diagonalizable. 4.2 True or False: If T : R³ → R³ is a linear transformation so that T(ej) = T(e2 – e3), then T is not invertible (i.e. AT is not invertible.) 4.3 True or False: If P, Q, and R are distinct points in R so that PQ x PR = 0, then P, Q, and R all lie on a single line.
