In the image you provided, the task is to identify the range of a set of points and determine if the set describes a function. The following information can be extracted:

1. Range of the Set of Points:

The range is the set of all the distinct y-values from the points provided. The range given in the image is: $\text{Range} = \{12, 9, -9\}$ These values represent the different y-coordinates, listed only once each.

2. Does the Set of Points Describe a Function?

A relation is a function if every x-coordinate (input) corresponds to exactly one y-coordinate (output). Without seeing the specific set of points, we cannot definitively answer this, but we can assume that if any x-value corresponds to more than one y-value, the relation would not be a function.

If you can provide the specific set of points (with both x and y coordinates), I can help you determine whether or not the set describes a function.

Do you have the points listed, or would you like to clarify further?
