2D Transformation (10 points) (1) (2 pts) Let A be the 3 x 3 2D transformation matrix for refelction about the L-axis. Show A. (2) (2 pts) Let RO) be the 3 x 3 2D transformation matrix for rotation by 0 about the origin (0,0). Show R(0). (3) (6 pts) Let B be the 3 x 3 2D transformation matrix for relfection about the line r = y. Express B as a composition of A and RO) and compute its value. Make the final result as simple as possible. (You should not need a calculator for calculations that may be required.)
