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
