Question

A relation R is defined from { 2 , 3 , 4 , 5 } to { 3 , 6 , 7 , 10 } by x R y ⇒ x is relatively prime to y , then domain of R is, { 2 , 3 , 5 }, 3 , 5, 2 , 3 , 4, 2 , 3 , 4 , 5

MARKS App · Accepted Answer

Given, x R y ⇒ x is relatively prime to y . R = { 2 , 3 , 2 , 7 , 3, 7 , 3, 10 , 4 , 3 , 4 , 7 , 5 , 3 , 5 , 6 , 5 , 7 } ∴ Domain of R = { 2 , 3 , 4 , 5 }
