Answer:

  • D: {-5, -2, 1, 5, 7}
  • R: {4, 10, 11, 15}

Step-by-step explanation:

You want the domain and range of the relation in the given table.

Domain

In a table of x- and y-values, you can replace the headings with ...

  x ⇒ Domain

  y ⇒ Range

The domain is the set of first values of a list of (x, y) ordered pairs. We usually like to see sets listed in order with duplicates eliminated. (If there are any duplicate x-values, the relation is not a function. This relation is a function.)

  domain: {-5, -2, 1, 5, 7}

Range

The range is the set of second values of a list of (x, y) ordered pairs. We usually like to see sets listed in order with duplicates eliminated.

  range: {4, 10, 11, 15}
