Let d, f, and g be defined as follows. . d: {0, 1)4 -> {0, 1)4. d(x) is obtained from x by removing the second bit and placing it at the end. For example, f(1011) = 1110. . f: (0, 1]4 -> {0, 1]4. f(x) is obtained from x by replacing the last bit with 1. For example, f(1000) = 1001. . g: {0, 1}4 -> {0, 1]3. g(x) is obtained from x by removing the first bit. For example, g(1000) = 000. (a) What is the range of go f? (b) What is f o d(1011)
