Concepts

The domain of a function is all the possible x-values for that function. In other words, it's all the x-coordinates listed in the graph.

Application

In this case, we have to list the domain of the given function. To do this, we have to first label the points, and then list their x-coordinates in increasing order.

Solution

Points:

• (1, 4)
• (2, 3)
• (3, 2)
• (4, 1)

X-Coordinates:

• 1, 2, 3, 4

Domain:

• {1, 2, 3, 4}
