In this exercise, lets agree to write the coordinates (x, y) of a point in the plane as the 2 1 matrix (a) Let A and Z Compute the matrix AZ. After computing AZ, observe that it represents the point obtained by reflecting about the x-axis. (b) Let B and Z Compute the matrix BZ. After computing BZ, observe that it represents the point obtained by reflecting about the y-axis. (c) Let A, B, and Z represent the matrices defined in parts (a) and (b). Compute the matrix (AB)Z, and then interpret it in terms of reflection about the axes.
