Reconocer una composición de funciones | Khan Academy en Español

Summary

This video covers the concept of function composition and its applications in algebra and calculus. The presenter starts by defining two functions, f(x) = 1 + x and g(x) = cos(x), and demonstrates how to compose them. The video explains how to substitute g(x) into f(x) to create a composite function. It also explores different ways to express functions as compositions of other functions, such as using sine and cosine functions. The content serves as a review and a foundation for understanding key calculus concepts like the chain rule.
