Q2 (8 points) Let A = {1, 2, 3, 4}. Let f : A - A be defined as f(1) = 4, f(2) = 1, f(3) = 2, f(4) = 3. Let g : A - A be defined as g(1) = 3, g(2) = 4, g(3) = 4, g(4) = 2. . Is f one-to-one? onto? invertible (if yes, specify the inverse)? Justify your answers. . Is g one-to-one? onto? invertible (if yes, specify the inverse)? Justify your answers. . If possible, compute f . g. . If possible, compute go f. + Drag and drop an image or PDF file or click to browse
