1. The problem asks us to determine the range of the function given the points on its graph. 2. The range of a function is the set of all possible output values (y-values). 3. From the graph, the points are approximately (3,4), (4,3), (5,2), and (6,1). 4. Extract the y-values from these points: 4, 3, 2, and 1. 5. Arrange these y-values in increasing order: 1, 2, 3, 4. 6. Since these are discrete points, the range is the set of these y-values. 7. Therefore, the range of the function is $$\{1, 2, 3, 4\}$$.
