Question

A domain consists of the values 1, 2, 3, and 2. A range consists of the values 5, 10, 15, and 20. The 1 in the domain corresponds to the 5 in the range, the first 2 in the domain corresponds to the 10 in the range, the 3 in the domain corresponds to the 15 in the range, and the second 2 in the domain corresponds to the 20 in the range. Does this relation represent a function? Explain.(1 point)

It does not represent a function. The domain value of 2 corresponds to two values within the range.

It does not represent a function. Each value in the domain corresponds to exactly one value in the range.

It does represent a function. Each value in the domain corresponds to exactly one value in the range.

It does represent a function. The domain value of 2 corresponds to two values within the range.

Answer 1

It does not represent a function. The domain value of 2 corresponds to two values within the range.

Explanation:

Answer 2

It does not represent a function. The domain value of 2 corresponds to two values within the range.

Explanation:

Given the function:

Domain : Range

1 => 5

2 => 10

3 => 15

2 => 20

For a relation to be considered a function, every domain value should have exactly 1 range value assigned to it or mapped to it.

In order words, a domain value should not have different range values.

In the relation given, domain value of 2, has more than 1 range value, 10 and 20, assigned to it. It does not have exactly 1 range value.

Therefore, the relation does not represent a function because the domain value of 2 corresponds to two values (10 and 20), within the range.
