There is one-one correspondence between the elements of the set A and the set B..Relations and Functions-, Types of Functions
>Relation from a set A to a set B is a subset of A x B. - A relation R on a set A is reflexive if a R a, " a A- A relation R on a set A is symmetric if a R b b R a. - A relation R on a set A transitive if a R b and b R c a R c. A relation R is said to be an equivalence relation on A if it is reflex..
Following are the types of Functions:
(1) One-one function (2) Many-one function (3) Onto function (4) Into function Let the relation be from set A to set ..
Many-one function
Every one element of A corresponds to more than one element of B. In example 3, one image has three pre-images. In example 4, one image has four pre-images. Therefore, many-one relations in examples 3 and 4 are many-one functions..

Summary - Reproduction is defined as the production of individuals of the same species, that is the next generation of the species. There are basically two types of reproduction - asexual and sexual. Asexual reproduction involves only one parent and the offspring is genetically ..
Naming Compounds With More Than One Different Functional Groups
When the molecule contains two or more dissimilar functional groups, the parent chain is so chosen so as to contain maximum possible number of functional groups. The numbering of the parent chain is done so that the functional group of higher priority gets the lo..
Naming Compounds with More Than One Similar Functional Groups
When a molecule contains more than one similar functional groups, then, the word di (for 2), tri (for 3), etc., is added before the secondary suffix, of the functional group. While adding such words, the vowel 'e' of primary suffix is retained. For example: Here, Word ..
