Question:

Let A= {l, 2, 3} and B = {2, 4, 6}. For each relation between A and B given as a subset of A x B, decide whether it is a function mapping A into B. If it is a function, decide whether it is one to one and whether it is onto B.
a. {(1, 4), (2, 4), (3, 6)}

b. {(l, 4), (2, 6), (3, 4)}
c. {(1,6),(1,2),(1,4)}

d. {(2, 2), (1, 6), (3, 4)}
e. {(1, 6), (2, 6), (3, 6)}
f. {(1, 2), (2, 6), (2, 4)}
