1. Let A = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} and f, g: A A two functions defined by f(n) = (3n) mod 10 and g(n) = (4n) mod 10. For each of the two functions, say whether it is (a) (6 points) injective; (b) (6 points) surjective; (c) (6 points) one-to-one; (d) (6 points) If the function is one-to-one, give its inverse. (Hint: The function inverse is written as kn mod 10.)
