Answer :
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.
