Let's clarify the domain and range based on the given sets of ordered pairs.
Ordered pairs: { (-1, 1), (-3, 3), (5, -5), (-7, 7) }
-
Domain: This is the set of all the first elements (x-values) from the ordered pairs.
- From the pairs, we extract the x-values: -1, -3, 5, and -7.
- Thus, the domain \( d \) is: \[ d = {-7, -3, -1, 5} \]
-
Range: This is the set of all the second elements (y-values) from the ordered pairs.
- From the pairs, we extract the y-values: 1, 3, -5, and 7.
- Thus, the range \( r \) is: \[ r = {-5, 1, 3, 7} \]
So, summarizing:
- Domain: \( d = {-7, -3, -1, 5} \)
- Range: \( r = {-5, 1, 3, 7} \)
