Yes, this relation is function.

Answer:

Relation  (12,7) (9, 10) (7,0) (5,3) are functions because each x value, each element in the domain, has one and only one y value, or one and only number in the range.

Note:

Remember if a domain element repeats then it's not a function

Answer:

Yes

Step-by-step explanation:

The rule is

A relation is called to be a function if every domain has an unique range

  • f(x)=y

Lets check
