Question

Suppose that the relation H is defined as follows.

H={(-1, -9), (4, 9), (9, -9)}
Give the domain and range of H.
Write your answers using set notation.

Answer 1

The domain of H is {-1, 4, 9} and the range of H is {-9, 9}.

Step-by-step explanation:

The domain of a relation is the set of all input values, or x-values, in the relation. In this case, the x-values are -1, 4, and 9. So, the domain of H is { -1, 4, 9 }.

The range of a relation is the set of all output values, or y-values, in the relation. In this case, the y-values are -9 and 9. So, the range of H is { -9, 9 }.
