Question

suppose that the relation h is defined as follows.
h = {(4, -4), (-9, 4), (-5, 0), (-5, -7)}
give the domain and range of h.
write your answers using set notation.

domain:
range:

Explanation:

Step1: Identify domain values

The domain of a relation is the set of all first elements from the ordered pairs. From $H=\{(4, -4), (-9, 4), (-5, 0), (-5, -7)\}$, the first elements are 4, -9, -5, -5. We only list unique values.
Domain set: $\{4, -9, -5\}$

Step2: Identify range values

The range of a relation is the set of all second elements from the ordered pairs. From the ordered pairs, the second elements are -4, 4, 0, -7. All values are unique.
Range set: $\{-4, 4, 0, -7\}$

Answer:

domain: $\{4, -9, -5\}$
range: $\{-4, 4, 0, -7\}$
