Answer:
D.
Step-by-step explanation:
The range is the (y) value. And you never repeat a number when finding the relation or domain (x). Therefor the best answer would be D.
Its not A because the numbers are for the domain (X value; First column)
Not B because its also for the Domain and it repeats -1 twice
Not C because it repeats 2 twice
Making D the reasonable answer
