Question

Give the domain and range of G={(6.0),(-9,-3),(1,-3)}

Answer 1

9514 1404 393

Answer:

• domain: {-9, 1, 6}
• range: {-3, 0}

Step-by-step explanation:

The domain is the list of the first numbers of the ordered pairs. If there are any duplicates, the relation is not a function. Here, the first numbers are {6, -9, 1}. Most folks find it convenient to list them in numerical order:

  {-9, 1, 6} . . . . domain of G

__

The range is the list of second numbers of the ordered pairs. Only the distinct values are reported. Here, the second numbers are {0, -3, -3}.

  {-3, 0} . . . . range of G
