Let A = {1, 2, 3, 4}, B = {1, 5, 9, 11, 15, 16} and f = {(1, 5), (2, 9), (3, 1), (4, 5), (2, 11)}. Is the following true?
f is a function from A to B
Justify your answer in case.

True
False

उत्तर
This statement is False.
Explanation:
Since (2, 9), (2, 11) f i.e., f contains two ordered pairs with the same first element. Hence, f is not a function from A to B.
