The range of the given relation is D. R = {-1, 3, 5, 8}.
Step-by-step explanation:
Step 1:
The range of a relation is the second set of values while the domain constitutes the first set of values.
There are 4 given relations with two sets of values so there would be 4 domain values and 4 range values.
Step 2:
The range of (1, -1) = -1,
The range of (2, 3) = 3,
The range of (3, 5) = 5, 
The range of (4, 8) = 8.
Combining these values we get the range as {-1, 3, 5, 8} which is option D.
 
        
             
        
        
        
Since the number is 8 you round up so it's 9.0
