Find the 3x3 matrices that produce the described composite 2D transformation, using homogeneous coordinates. (a) Translate by (2,2), rotate 90° about the original and then reflect in y-axis. (b) Translate (-1, 2), and then scale 2 in x-coordinate and 3 in y-coordinate. (c) Reflect in the original, translate by (-1, 1) and then scale 0.5 in x-coordinate. (d) Translate (2,3), reflect in y=x, and then rotate 30° about the original.
