Answer:
9
Step-by-step explanation:
Ordered pairs are written in the format (x, y).
The range is all of the possible y-values in a relation.
To find range, write out all of the possible y-values without repeats.
Range = {0, 5, 8, 9}
Choose the greatest value out of the above numbers.
9 is greater than all of the other numbers.
9 is the value of the greatest element in the range of this relation.
