Answer:

  d: {-5, 0, 8}

  r: {-6, -3, 1, 8}

Step-by-step explanation:

You want the domain and range of the relation T= {(-5, -3), (8, -6), (-5, 1), (0,8)}.

Domain

The domain is the set of first values. We usually like to see duplicates eliminated and the values written in increasing order:

  {-5, 0, 8}

Range

The range is the set of second values. Again, we like them in order:

  {-6, -3, 1, 8}

__

Additional comment

If there are duplicates among the domain values (as here), the relation is not a function.
