Multiple Choice Question :
The range of the relation R = {(x, x2) | x is a prime number less than 13} is ________
Options
{2, 3, 5, 7}
{2, 3, 5, 7, 11}
{4, 9, 25, 49, 121}
{1, 4, 9, 25, 49, 121}
Solution
{4, 9, 25, 49, 121}
Explanation;
Prime number less than 13 = {2, 3, 5, 7, 11}
Range (R) = {(x, x2)}
Range = {4, 9, 25, 49, 121} .......(square of x)
