Relations Domain and Range

What is the definition of range and domain in mathematics?

• The range is the set of all possible x values, while the domain is the set of all possible x values.

• The range is the set of all possible x values, while the domain is the set of all possible y values.

• The range is the set of all possible y values, while the domain is the set of all possible x values.

• The range is the set of all possible y values, while the domain is the set of all possible y values.

State the domain of the following relation:

{(1, 5), (3, 7), (6, 8), (8, 9), (3, 4)}

• {4, 5, 7, 8, 9}

• {1, 3, 6, 8}

• (1,5)

• {(1, 5), (3, 7), (6, 8), (8, 9), (3, 4)}

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.
