Learn the definitions, examples, and graphs of continuous and discrete functions. A continuous function allows any x-value in an interval, while a discrete function only allows certain x-values, usually integers.
In discrete mathematics, particularly in graph theory, a graph is a structure consisting of a set of objects where some pairs of the objects are in some sense "related". The objects are represented by abstractions called vertices (also called nodes or points) and each of the related pairs of vertices is called an edge (also called link or line).
