Question

NEED ASAP!!!

Look at this set of ordered pairs: (12,7) (9, 10) (7,0) (5,3) Is this relation a function? yes no​

Answer 1

Yes

Explanation:

The rule is

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

• f(x)=y

Lets check

• f(12)=7
• f(9)=10
• f(7)=0
• f(5)=3

Yes it's a function

Answer 2

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
