The vertical line test states that if we can draw any vertical line such that it intersects the graph of the set of points in more than one point, then the set of points does not represent a function. On the other hand, if we cannot draw any vertical line that intersects the graph in more than one point, then the set of points represents a function.
Let's plot the given points on a graph:
```
| *
3 | *
2 | *
1 | *
|
|
-2| *
|________
-2 1 2 8
```
From the graph, we can see that no two points have the same x-coordinate. Therefore, we cannot draw any vertical line that intersects the graph in more than one point. This means that the set of points represents a function.
Alternatively, we can check that each x-value is paired with only one y-value. For example, (-2,1) and (2,0) have different y-values even though they have the same x-value. Therefore, the set of points represents a function.
Therefore, the given set of points (-2,1), (1,3), (2,0), and (8,3) represents a function.
