Respuesta :
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
- f(12)=7
- f(9)=10
- f(7)=0
- f(5)=3
Yes it's a function
