Given:
The relation S is:
To find:
The domain and range of S.
Solution:
If a relation is defined by the set of ordered pairs (x,y), then the domain is the set of x-values and range is the set of y-values.
Let R be a relation defined as , then
and
.
The given relation is:
Here, x-values are 4,-9,0,6 and the y-values are 9,4,-9,6.
So, the domain and range of the given relation S are
Therefore, and
.
