Answer:
The given relation is not a function.
Explanation:
A relation is called a function if there exist a unique value of y for each value of x.
The given table is
x y
1 -2
1 -3
2 1
3 -2
From this table it is clear that we have two values of y at x=1.
One value of y at x=1 is -2 and the second value of y at x=1 is -3.
Since the given relation has more than one value of y for x=1, therefore the given relation is not a function.
