Functions and Relation

This app contains basic material of function and Relation.In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x2. The output of a function f corresponding to an input x is denoted by f(x) (read "f of x").
Following parts of function are discussed in the app
1) Cartesian Product of sets
2) Relation
3) Types of function
4) Surjective function
5) Injective function
6) Bijective function
7) Composition of function
This app is especially useful for students preparing for CBSE, ICSE and IITJEE
