The domain is whatever you want it to be. In the absence of a domain being defined explicitly, it is taken to be the whole of the real line.

define or describe each set of real numbers?

A set "A" is said to be a subset of "B" if all elements of set "A" are also elements of set "B".Set "A" is said to be a proper subset of set "B" if: * A is a subset of B, and * A is not identical to B In other words, set "B" would have at least one element that is not an element of set "A". Examples: {1, 2} is a subset of {1, 2}. It is not a proper subset. {1, 3} is a subset of {1, 2, 3}. It is also a proper subset.

The universal subset is the empty set. It is a subset of all sets.

A number does not have a subset.

ray and segment

A line has infinitely many subsets, not just three. Any collection of points on the line constitute a subset.

By: Tedd Mikhail Ulit ( sori yan lang po yung nasa libro eh :)) The line, itself, is a subset (though not a proper subset). A ray is a subset of a line with one end-point which extends in only one direction. A line segment is a subset of a line with two end points. A point is a subset of a line. Finally, nothing is a subset (the null subset) of a line.

A subset of a line is a part of the line that consists of one or more points on the line. It is a portion of the line that may include endpoints or extend indefinitely in one or both directions.

A line is an abstract geometric concept and there are no substances in a line.

different subset of a line

The various subsets are:The empty set: nothing.A point: a position on the line with 0 dimensions.A line segment: a 1-dimensional finite subset such that, if x and y are any two points in the subset then so is mx + (1-m)y from any m in [0,1]. That is, all points between x and y are also in the set.A ray: a 1-dimensional subset such that one of the points x and y is an infinite distance away.Collections of a finite or infinite number of points, line segments and rays.The line itself.For lines and rays, the end points may or may not be part of the subset.

A line segment would be a subset of a line. You wold draw two closed dots with a line joining them.
