Let A = 124 316 k 3 2 . (a) In terms of k, find the volume of the parallelepiped determined by the row vectors of the matrix A. (b) Does your answer to (a) change if we instead consider the volume of the parallelepiped determined by the column vectors of the matrix A? Why or why not? (c) For what value(s) of k, if any, is A invertible?
