Question

Determine whether the following relation represents a function. Give the domain and range for the relation. StartSet (7 comma 2 )comma (5 comma negative 4 )comma (3 comma 3 )comma (negative 4 comma negative 4 )EndSet

Answer 1

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.
