Answer:
- Domain: {-2,-1,0,1,}
- Range:{0,1,2}
- It is a function
Step-by-step explanation:
The function is defined with ordered pairs:
{(-2, 1), (-1,0), (0, 1), (1, 2) }
The domain in this case is the set of all the x-coordinates.
Domain: {-2,-1,0,1,}
The range in this case refers to the set of all the y-coordinates.
Range:{0,1,2}
Note that in listing the elements of a set, we list distinct entries only.
The given relation is a function because there is no x-coordinate that appears more than once in the ordered pairs with different y-coordinates.
