Answer:
The relation is discrete function
Domain is x
Range is y
Explanation:
I. This function is discrete because x = 2,2,2
and y = 4, -1, -3
Or (2,4), (2,-1) and (2,-3)
If this function is continuous, the x and y will be something like this -3 <= x <= 3
II. Domain is x.value
III. Range is y.value
Ask me for anything.
