Exercise 4 For each matrix M listed below, consider the product M . v where u is the homogeneous coordinates of a point in two-space. State whether this operation carries out a translation, rigid motion, scale transformation, invertable affine transformation, or degenerate affine transformation; whether or not it leaves the origin fixed; and whether or not it is a reflection. Note that | (0.28, 0.96) | = 1. Given that fact, you should be able to do these by inspection, without putting pencil to paper, let alone running MATLAB. 0.28 -0.96 0 0.28 0.96 0.96 0.28 0.96 0.28 0 -0.96 0.28 3 0.28 -0.96 2 0 0 0 0 0 0 3 2.8 -9.6 0 0.96 0.28 0 0 9.6 2.8 0 0.28 0.96 O HN O O 0 0 1 0 0 H IN 0 4 8 HO O O O
