Question

write the relation in the roster form. state it's domain and range R3={(x,y)/y=3x,y€{3,6,9,12},x€={1,2,3,}​

Answer 1

Answer:

solution: Let , A={1,2,3}and B={3,6,9,12}

given, R= {(x,y):y =3x and x €A and y€B}

•°•R= {(3,1),(6,2),(9,3)}

Now, domain (R) = (3,6,9)

and range (R)= (1,2,3)
