Question

Suppose that the relation H is defined as follows.
H={(-2,5),(-7,0),(1,5)}
Give the domain and range of H Write your answers using set notation.
domain=
range=

Answer 1

The domain of H is the set of all x-values in the relation H. From the given relation, the x-values are -2, -7, and 1.

So, the domain of H is {-2, -7, 1}.

The range of H is the set of all y-values in the relation H. From the given relation, the y-values are 5 and 0.

So, the range of H is {5, 0}.
