Solve and draw graphs: a) Consider a square with coordinates (1,-1) (3,-1) (1,-3) (3,-3). Translate the square 3 units with respect to xaxis and 2 units with respect to y-axis. b) Scale the above translated square in x-direction by a factor 0.5 and in y-direction by a factor 2. What changes were expected if the above scaling factored were reversed. c) Apply a shear in y-direction by 2 units on the above scaled square. How shear would affect the scaled square if it would have been applied in x-direction. d) Consider a triangle with coordinates (0,0) (-3,0) (-3,-3). Rotate the triangle in anticlockwise direction by an angle of 30.
