What is a Composition Function?

A composition function is a type of mathematical function that combines two or more functions in order to create a new function. In essence, it is the combination of two or more functions that produces a single resulting function. In mathematics, composition functions are used to represent relationships between different objects or properties.

What is the Formula for a Composition Function?

The formula for a composition function is fairly simple. The two functions being combined are first put into two variables, f and g. The resulting composition function is then written as (f o g). This means that the output of the first function f is used as the input for the second function g.

Examples of Composition Function

A simple example of a composition function would be the combination of two functions, f(x) = x2 and g(x) = x + 2. This composition function (f o g)(x) would result in the following expression: (x2) + 2. This expression can be written as x2 + 2, which is the final result.

How to Solve a Composition Function

When solving a composition function, the first step is to identify the two functions that are being combined. Once the two functions have been identified, it is then possible to calculate the resulting composition function. The calculation is done by substituting the output of the first function into the input of the second function.

Contoh Soal Fungsi Komposisi

Contoh soal fungsi komposisi berikut ini akan membantu Anda memahami lebih lanjut tentang cara menggunakan fungsi komposisi. Contoh soal ini berfokus pada fungsi komposisi dengan dua atau lebih variabel.

Contoh 1:

Diberikan fungsi f(x) = x2 + 5 dan g(x) = x - 3, temukan fungsi komposisi (f o g)(x).

Solusi: Cara menyelesaikan masalah ini adalah dengan mengganti keluaran fungsi f(x) sebagai masukan fungsi g(x). Dengan demikian, fungsi komposisi (f o g)(x) adalah (x2 + 5) - 3, yang dapat ditulis sebagai x2 + 2.

Contoh 2:

Diberikan fungsi f(x) = x2 + 2 dan g(x) = x3 - 5, temukan fungsi komposisi (f o g)(x).

Solusi: Cara menyelesaikan masalah ini adalah dengan mengganti keluaran fungsi f(x) sebagai masukan fungsi g(x). Dengan demikian, fungsi komposisi (f o g)(x) adalah (x2 + 2)3 - 5, yang dapat ditulis sebagai x6 + 6x3 + 4.

Conclusion

Composition functions are an important concept in mathematics that allow two or more functions to be combined into a single resulting function. In order to solve a composition function, the two functions must first be identified, and then the resulting function can be calculated by substituting the output of the first function into the input of the second function. Examples of composition functions and how to solve them can help clarify this concept.
