Question

IfR, "is a divisor of' is a relation from the set A= {1,2,3} to the set B = {4, 10, 15)
Write R in roster form. Also write its domain and range.​

Answer 1

Answer:

see in step by step explanation

Step-by-step explanation:

Under this relation (R), we have

R = {(4, 5); (4, 7); (4, 9); (6, 7); (6, 9), (8, 9) (2, 5) (2, 7) (2, 9)}

Therefore, Domain (R) = {2, 4, 6, 8} and Range (R) = {1, 5, 7, 9}
