In math, the relation is between the x-values and y-values of ordered pairs. Note that the order in the set does not matter. Range: {3, 4}. Discrete Mathematics − It involves distinct values; i.e. In math, a relation is just a set of ordered pairs. The domain is the set of all x-values, which is represented in the first cluster. Discrete mathematics is the branch of mathematics dealing with objects that can assume only distinct, separated values. A binary relation R from set x to y (written as xRy or R(x,y)) is a The brackets are used to show that the values form a set. For example, if we have a finite set of objects, the function can be defined as a list of ordered pairs having Each of those displays provide a way for us to list the correct ordered pairs. 12, Jan 18.

The notation aRb means (a Then, we will express the relation as a set of ordered pairs: In a mapping, the domain is the set of values in the first cluster, and the range is the set of values in the second cluster. Relations are subsets of two given sets. - is a pair of numbers used to locate a point on a coordinate plane; the first number tells how far to move horizontally and the second number tells how far to move vertically. These relations are related to recursive algorithms. Expert Answer 100% (1 rating) Previous question Next question Transcribed Image Text from this Question. Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous.In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics – such as integers, graphs, and statements in logic – do not vary smoothly in this way, but have distinct, separated values.
