\{(-11,11), (-8,8), (0,0), (13,-13)\}
\][/tex]

A. Domain: [tex]\(-11 \leq x \leq 13\)[/tex]
Range: [tex]\(-13 \leq y \leq 11\)[/tex]

B. Domain: [tex]\(\{-13, 0, 8, 11\}\)[/tex]
Range: [tex]\(\{-11, -8, 0, 13\}\)[/tex]

C. Domain: [tex]\(-13 \leq x \leq 11\)[/tex]
Range: [tex]\(-11 \leq y \leq 13\)[/tex]

D. Domain: [tex]\(\{-11, -8, 0, 13\}\)[/tex]
Range: [tex]\(\{-13, 0, 8, 11\}\)[/tex]



Answer :

To determine the domain and range of the function represented by the given set of ordered pairs [tex]\(\{(-11, 11), (-8, 8), (0, 0), (13, -13)\}\)[/tex], we follow these steps:

1. Extract the Domain:
The domain consists of all the first elements (x-coordinates) in the set of ordered pairs.

- From the ordered pair [tex]\((-11, 11)\)[/tex], the first element is [tex]\(-11\)[/tex].
- From the ordered pair [tex]\((-8, 8)\)[/tex], the first element is [tex]\(-8\)[/tex].
- From the ordered pair [tex]\((0, 0)\)[/tex], the first element is [tex]\(0\)[/tex].
- From the ordered pair [tex]\((13, -13)\)[/tex], the first element is [tex]\(13\)[/tex].

Thus, the domain is [tex]\(\{-11, -8, 0, 13\}\)[/tex].

2. Extract the Range:
The range consists of all the second elements (y-coordinates) in the set of ordered pairs.

- From the ordered pair [tex]\((-11, 11)\)[/tex], the second element is [tex]\(11\)[/tex].
- From the ordered pair [tex]\((-8, 8)\)[/tex], the second element is [tex]\(8\)[/tex].
- From the ordered pair [tex]\((0, 0)\)[/tex], the second element is [tex]\(0\)[/tex].
- From the ordered pair [tex]\((13, -13)\)[/tex], the second element is [tex]\(-13\)[/tex].

Thus, the range is [tex]\(\{-13, 0, 8, 11\}\)[/tex].

Now, we compare these findings with the provided choices:

A.
- Domain: [tex]\(-11 \leq x \leq 13\)[/tex]
- Range: [tex]\(-13 \leq y \leq 11\)[/tex]

B.
- Domain: [tex]\(\{-13, 0, 8, 11\}\)[/tex]
- Range: [tex]\(\{-11, -8, 0, 13\}\)[/tex]

C.
- Domain: [tex]\(-13 \leq x \leq 11\)[/tex]
- Range: [tex]\(-11 \leq y \leq 13\)[/tex]

D.
- Domain: [tex]\(\{-11, -8, 0, 13\}\)[/tex]
- Range: [tex]\(\{-13, 0, 8, 11\}\)[/tex]

From the analysis, it is clear that:

- The domain [tex]\(\{-11, -8, 0, 13\}\)[/tex] matches the domain provided in choice D.
- The range [tex]\(\{-13, 0, 8, 11\}\)[/tex] matches the range provided in choice D.

Therefore, the correct answer is:
D. Domain: [tex]\(\{-11, -8, 0, 13\}\)[/tex]
Range: [tex]\(\{-13, 0, 8, 11\}\)[/tex]
