Question

The range of the relation R = {(x, x²) a prime number less than 13} is …

(1) {2, 3, 5, 7} 

(2) {2, 3, 5, 7, 11} 

(3) {4, 9, 25, 49, 121} 

(4) {1, 4, 9, 25, 49, 121}

Answer 1

(3) {4, 9, 25, 49, 121}

Prime number less than 13 = {2, 3, 5, 7, 11} 

Range (R) = {(x, x²)} 

Range = {4, 9, 25, 49, 121} (square of x)
