Answer:

  • is a function
  • domain: {-4. 3. 5. 7}
  • range: {-4, 2, 3}

Step-by-step explanation:

Given:

  {(7, 2), (5, -4), (3, 3), (-4, -4)}

__

The domain is the set of first numbers:

  {7, 5, 3, -4} . . . domain

The range is the set of second numbers:

  {2, -4, 3} . . . range

No domain values are repeated, so this relation is a function.
