composite function
[/kəmˈpɑːzɪt ˈfʌŋkʃən/]
nounfemininepl: composite functions / funções compostas
função composta
1. A function formed by the combination of two or more functions, where the output of one function becomes the input of another function
If f(x) = 2x and g(x) = x + 3, then the composite function (f ∘ g)(x) = f(g(x)) = 2(x + 3) = 2x + 6
Se f(x) = 2x e g(x) = x + 3, então a função composta (f ∘ g)(x) = f(g(x)) = 2(x + 3) = 2x + 6
2. In mathematics, the operation of applying one function to the results of another function, denoted by the symbol ∘
The composite function h = f ∘ g means h(x) = f(g(x))
A função composta h = f ∘ g significa h(x) = f(g(x))
This is a technical mathematical term with no cultural variations between Brazil and the United States. It is universally used in mathematics education, calculus courses, and academic contexts. The notation f ∘ g is internationally standardized and recognized across all English and Portuguese-speaking mathematical communities.
