Composite Function
A composite function is created when one function is applied to the result of another function. For two functions and , the composite function is defined by , which means the output of is used as the input of . The notation is read as ' composed with ' or ' of .' It is important to note that is different from the product of two functions : composition means substituting one function into the other, whereas multiplication means multiplying the output values of the two functions together. Additionally, function composition is generally not commutative — the order in which functions are composed matters, so does not necessarily equal .
