If R={(2,5),(4,7),(6,9)}, what is the range of R?

Answer and explanation

Correct answer: {5,7,9}

The governing concept is the range of a relation. The range is the set of all second components, or output values, appearing in its ordered pairs. In R, the pairs are (2,5), (4,7), and (6,9). Their first components are 2, 4, and 6, so the domain is {2,4,6}. Their second components are 5, 7, and 9, so the range is {5,7,9}. Therefore option B is correct. Option A gives the domain, not the range. Option C mixes first and second components, while option D reverses the ordered pairs and therefore is not a set of range values. If a second component were repeated, it would still be listed only once because a set does not contain duplicate elements.
