 Pairs of points .

Plot the order of pairs.

graph coordinates points (-1,5), (1,3), (4,3), (2,-4)

The relation is

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

The domain of the relation is:

The range of the relation is the set of second (y-coordinates) coordinates.

The range of the relation is

 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 and this one-to-one function.

The graph consists of points that are not connected. So the relation is discrete.


Yes, the relation is a function and discrete.
