1. Let f:Z → Z be defined by f(x) = x + 1
(a) Determine f[Z] ( = ran(f)). (Do not give specificexamples.)
(b) Is f surjective? If f is not surjective, provide acounterexample to show why it is not surjective.
2. Let g:Z → Z be defined by g(x) = 4x + 8
(a) Determine f[Z] ( = ran(g)). (Do not give specificexamples.)
(b) Is g surjective? If g is not surjective, provide acounterexample to show why it is not surjective.
3. Write down the injective (one-to-one) functions from P toQ.
(a) P = {a, b} and Q = {1, 2}
(b) P = {c, e} and Q = {2, 4, 6}
