Distinction Between Function Composition and Function Multiplication
It is critical to distinguish between the composition of two functions, denoted as , and the multiplication of two functions, denoted as . Function composition involves substituting the entire output expression of one function into the input variable of the other, effectively nesting them such that . In contrast, function multiplication involves evaluating each function independently and then multiplying their resulting outputs together, defined algebraically as . Because they rely on fundamentally different operations, composition and multiplication will generally produce completely different algebraic expressions and numerical values.
