Which set of ordered pair represent function from A = {1, 2, 3, 4}to B = {−1, 0, 1, 2, 3}? Justify : {(1, 1), (2, 1), (3, 1), (4, 1)} - Mathematics and Statistics

Which set of ordered pair represent function from A = {1, 2, 3, 4}to B = {−1, 0, 1, 2, 3}? Justify : {(1, 1), (2, 1), (3, 1), (4, 1)}

Sum

{(1, 1), (2, 1), (3, 1), (4, 1)} represents a function
Reason:
Every element of set A has been assigned a unique image in set B.
