Answer:
All numbers that are in range are:
-2,0 and 2
Step-by-step explanation:
The range of a relation is the set of the second coordinates from the ordered pairs.
i.e. if (x,y) is a ordered pair
then, range contains y
Here, we are given a relation:
R = {(-3, -2), (-3, 0), (-1, 2), (1, 2)}
So, the numbers which are in range are:
-2, 0, 2
Hence, all numbers that are in range are:
-2,0 and 2
