(a) Explanation Graph: The complete bipartite graph with m vertices in the 1 s t partition set and n vertices in the 2 n d partition set is denoted by k m , n . For, k m , n , the vertices in the 1 s t partition set will all be of degree n , while the degree of vertices in the 2 n d partition set will be m . Graphs are bisectors if graphs can be mapped so that each of their vertices and their edges are symmetrical to each other. Some commonly used methods are listed below to show that the two underlines are not isomorphic: Any of the following properties differ for the graphs: The number of vertices. The number of edges. An isomorphism only maps one graph to another on the other graph, so the isomorphic graph will have the same number of cycles of a given length (b) To determine To graph: The graph is on the right isomorphic to κ 4 , 4

Minimization

In mathematics, traditional optimization problems are typically expressed in terms of minimization. When we talk about minimizing or maximizing a function, we refer to the maximum and minimum possible values of that function. This can be expressed in ter…

Maxima and Minima

The extreme points of a function are the maximum and the minimum points of the function. A maximum is attained when the function takes the maximum value and a minimum is attained when the function takes the minimum value.

Derivatives

A derivative means a change. Geometrically it can be represented as a line with some steepness. Imagine climbing a mountain which is very steep and 500 meters high. Is it easier to climb? Definitely not! Suppose walking on the road for 500 meters. Which …

Concavity

In calculus, concavity is a descriptor of mathematics that tells about the shape of the graph. It is the parameter that helps to estimate the maximum and minimum value of any of the functions and the concave nature using the graphical method. We use the …
