The domain of the relation is the set of all first (x-coordinates) coordinates.

Draw the vertical lines through the points. Observe that there
\is no vertical line contains more than one of the points.
\This graph passes the vertical line test.

Each element of the domain is paired with exactly one element of the range. Therefore the relation is a function. The graph consists of points that are not connected. So, the relation is discrete.

Yes, the relation is a function and discrete.
