Is an identify function one-one function ?

All onto functions are one-one functions

Injective function(one-one function) and Many- one function

Statement-1 : If f(x) and g(x) are one-one functions then f(g(x)) and g(f(x)) is also a one-one function. and Statement-2 The composite function of two one-one function may or many not be one-one.
