Use a mapping diagram to determine whether the relation is a function.(3,,8)(5,,,1)

it's not a function because 3 is mapped with 7,8, and 1, but in a function, each domain has only one range.

Below.

Step-by-step explanation:

3 >  7

3 > 8

5 > 2

4 > 5

3 > 1

This is not a function because 3 maps to 1, 7 and 8.

This is a one-to-many relation - a function can be only one-to-one or many-to-one.
