Math Problem Statement

Find the domain and the range of the given relation. {(0,3), (-9,2), (-1,-3), (-3,-1)}

Solution

To find the domain and range of the given relation, we need to identify all the unique xx-values and yy-values in the set of ordered pairs.

Given relation: {(0,3),(9,2),(1,3),(3,1)}\{(0, 3), (-9, 2), (-1, -3), (-3, -1)\}

Domain

The domain is the set of all possible xx-values in the relation.

  • From the pairs, the xx-values are: 00, 9-9, 1-1, and 3-3.
  • Therefore, the domain is: {0,9,1,3}\{0, -9, -1, -3\}.

Range

The range is the set of all possible yy-values in the relation.

  • From the pairs, the yy-values are: 33, 22, 3-3, and 1-1.
  • Therefore, the range is: {3,2,3,1}\{3, 2, -3, -1\}.

Summary

  • Domain: {0,9,1,3}\{0, -9, -1, -3\}
  • Range: {3,2,3,1}\{3, 2, -3, -1\}
