1.  Give the 3 × 3 matrix that represents the inverse of the transformation in Exercise II.8.

2.  Give an example of how two different 3 × 3 homogeneous matrices can represent the same affine transformation.

3.  Consider the transformation shown in Figure II.12. Suppose that a function drawF() has been written to draw the F at the origin as shown in the left-hand side of Figure II.12.

a. Give a sequence of pseudo-OpenGL commands that will draw the F as shown on the right-hand side of Figure II.12.

b. Give the 3 × 3 homogeneous matrix that represents the affine transformation shown in the figure.
