Why isn’t (1,0) (2,-3) (2,1) (-2,0) (1,1) (-2,-3) a function

Answer:

To determine whether a set of points represents a function, we need to check if each x-value is associated with only one y-value. In the given set of points (1,0), (2,-3), (2,1), (-2,0), (1,1), and (-2,-3), we can observe that some x-values are associated with multiple y-values.

For example, the x-value 2 is associated with both -3 and 1. In a function, each x-value should have a unique y-value. Since the point (2,-3) and (2,1) have the same x-value but different y-values, this set of points does not represent a function.

In summary, a set of points represents a function if each x-value is associated with only one y-value. In the given set of points, there are instances where an x-value is associated with multiple y-values, making it not a function.
