Answer:
The relation {(2,1),(3,2),(-1,1),(0,-2)} is a function because the domain {2,3,-1,0} and range {1,2,1,-2} of the relation is paired exactly only once.
Step-by-step explanation:
The given relation is {(2,1),(3,2),(-1,1),(0,-2)}.
It is required to determine the relation is a function.
Step 1 of 1
The given relation is {(2,1),(3,2),(-1,1),(0,-2)}.
This relation shows that the domain of the relation {2,3,-1,0} is paired with one element of the range {1,2,1,-2}.
Hence, the relation is a function.
