Answer to Question #77237 in Discrete Mathematics for muhammad hassan

Question

Q:1. Determine whether each set is a function from X = {1,2,3,4} to Y = {a,b,c,d}.
If it is a function, find its domain and range, draw its arrow diagram, and
determine if it is one-to-one, onto or both.
a) {(1,a,),(2,a),(3,c),(4,b)}
b) {(1,c),(2,a),(3,b),(4,c),(2,d)}
c) {(1,d),(2,d),(4,a)}

Q:2. List all possible functions from A to B, A = {a, b, c}, B = {0, 1}. Also indicate in
each case whether the function is one-to-one, is onto and one-to-one-onto.
