8. For each of the functions below, indicate whether the function is onto, one-to-one, neither or both. If the function is not onto or not one-to-one, give an example showing why. If the function is one-to-one and onto, give the inverse of the function. (a) f : {0,1}3 → {0, 1}³. The output of f is obtained by swapping the first and the last bits of x. For example f(110) : 011. (b) f : {0,1}4 → {0, 1}³. The output of f is obtained by replacing the last two bits with 0. For example f(1111) = 110. (c) f : {0,1}3 –→ {0, 1}4. The output of f is obtained by adding a 1 to the end of the string. For example f(100) = 1001.
