Answer with True or False. 1. The functions from Z to Z is onto if f(n)=n−1. 2. These function from {a, b, c, d} to itself is one to one if f (a) = d, f (b) = b, f (c) = c, f (d) = d. 3. These function from {a, b, c, d} to itself is onto if f (a) = b, f (b) = b, f (c) = d, f (d) = c. 4. These function from {a, b, c, d} to itself is onto if f (a) = b, f (b) = a, f (c) = c, f (d) = d.
