Answer:

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

Answer:

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.
