Question

Is R={ (1, 5), (2, 9), (3, 1) , (4, 5), (2, 11)} a relation from set A to set B , where A={1, 2, 3} and B={1, 5, 9, 11, 15, 16}, justify your answer.

Answer 1

Step-by-step explanation:

in the relation R first elements are called pre -image and second elements are called images

pre-images are related to A and images related to B

A={1,2,3,4}

B={5,9,1,11}

so above sets are wrong
