DefinitionComposition or composite function is a function that results from applying one function to the output of another. The idea of a composition of two functions f of g is a form of combination of two functions such that one function takes an input and output is supplied to other function mean f(g(x)) where we are giving output of g as an input to f. so is known as composite function (as one are composed on other ) are utilized widely in areas like calculus, algebra and functional analysis as imperative part to represent sequential processes & transformations. They are used to describe intricate correlations of variable and to scrutinize array of system behavior. In other words, if f(x)=x2 and g(x)=sin(x) then let us consider the function h(x)=f(g(x)). The composite function f◦g is f(g(x))=(sin(x))2, which is the square of the sine function.
