# Often asked: What Are Graphs In Math?

## What is graph and example?

A graph is a common data structure that consists of a finite set of nodes (or vertices) and a set of edges connecting them. For example, a single user in Facebook can be represented as a node (vertex) while their connection with others can be represented as an edge between nodes.

## What is called graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter. Each object in a graph is called a node.

## What is graph and types?

A simple graph with ‘n’ mutual vertices is called a complete graph and it is denoted by ‘Kn‘. In the graph, a vertex should have edges with all other vertices, then it called a complete graph. In other words, if a vertex is connected to all other vertices in a graph, then it is called a complete graph.

## Why do we use graphs in math?

Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space. If the data shows pronounced trends or reveals relations between variables, a graph should be used.

## How do you describe a graph?

Describing language of a graph

1. UP: increase / rise / grow / went up / soar / double / multiply / climb / exceed /
2. DOWN: decrease / drop / fall / decline / plummet / halve / depreciate / plunge.
3. UP & DOWN: fluctuate / undulated / dip /
4. SAME: stable (stabilised) / levelled off / remained constant or steady / consistent.

## What is a graph simple definition?

(Entry 1 of 4) 1: a diagram (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables.

## What are the basic graphs?

A basic two-dimensional graph consists of a vertical and a horizontal line that intersects at a point called origin. The horizontal line is the x axis, the vertical line is the y axis. In simple line graphs, the x and y axes are each divided into evenly spaced subdivisions that are assigned to numerical values.

## What is a general graph?

A general – graph G is a pair (V, E) where V is finite non empty set of vertices and E is a set of original edges and inverse edges. A special cases of a general – graph will be introduced as follows: Definition 5. An inverse- graph is a pair (V, ) where V is finite non empty set of vertices and is a set of inverse edges.

## When was a graph first used?

Eulerian refers to the Swiss mathematician Leonhard Euler, who invented graph theory in the 18th century.

## What are the two main types of graphs?

There are several different types of charts and graphs. The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs. They are generally used for, and are best for, quite different things.

## How do we use graphs in everyday life?

Graphs can be very useful to monitor pupose of the body like heart rate, blood sugar levels, cholesterol levels, temperature. If you have asthma for example, you might required to graph your peak expiatory flow every day on a chart to monitor your breathing.
