composite function
[composite function|composite function] is a function composed of two or more functions where the output of one function serves as the input to the next function.
Definition
composite function is a function composed of two or more functions where the output of one function serves as the input to the next function.
Mechanism
composite function Evaluating a composite function begins with the inner function, followed by the outer function using the inner function's results. The domain requires x to be in g's domain and g(x) to be in f's domain.
Examples
As discussed previously, the domain of composite function such as f ∘ g depends on the domain of g and the domain of f.
