Question

Let a={1,2,3] b={4,5,6,7} and let f={(1,4), (2,5) (3,6)} be a function from a to b show that f is one one

Answer 1

Step-by-step explanation:

It is given that A = {1, 2, 3}, B = {4, 5, 6, 7}.

f: A → B is defined as f = {(1, 4), (2, 5), (3, 6)}.

∴ f (1) = 4, f (2) = 5, f (3) = 6

It is seen that the images of distinct elements of A under f are distinct.

Hence, function f is one-one.
