Question

Determine whether the following relation is a function.
{(3,7), (3,8), (3,-2), (3.4),(3,1)}
A) it is a function because the ordered pairs all have the same x-value.
B) it is not a function because there are multiple y-values paired with a single x-value.
C) it is a function because none of the ordered pairs have the same y-value.
D) it is not a function because none of the ordered pairs have the same y-value.

Answer 1

B) it is not a function because there are multiple y-values paired with a single x-value.

Answer 2

Answer:

No; the domain value 3 corresponds to multiple range

Step-by-step explanation:

The domain value 3 corresponds to all range values: 7, 8, –2, 4, and 1.

A relation is not a function if any domain value corresponds to more than one range value.
