Question

Do the ordered pairs below represent a relation, a function, both a relation and a function, or neither a relation or a function?
(-2,3), (2,-7), (7,-12), (10,-15)

Answer 1

Answer:

Is a relation and a function.

Step-by-step explanation:

Every set of order pairs represent a relation.

Remember that a relation is a function when every element from the domain has a unique corresponding element in the range. In this case

f(-2) = 3

f(2) = 7

f(7) = -12

f(10) = -15

Therefore the relation is a function as well.
