LESSON 4 COMPOSITION FUNCTIONS AND INVERSE FUNCTIONS. 1. COMPOSTION FUNCTIONS. Definiton Let f and g be two functions. The composite function f g is the function defined by ( f g )( x ) f ( g ( x ) ) . The domain of f g is the set of all x in the domain of g such that g ( x ) is in the domain of f.
Introduction. The composition of two functions g and f is the new function we get by performing f first, and then performing g. For example, if we let f be the function given by f(x) = x2 and let g be the function given by g(x) = x + 3, then the composition of g with f is called gf and is worked out as gf(x) = g(f(x)) .
When finding the domain of composite functions: you must find the domain of the first function AND the composite function. Composite Functions + 11 Example: ý(x) What is the domain of gfflx)) ? 5x + 10 So, the domain is all real numbers except 11/5 2 or x

The term "composite" in mathematics, while seemingly simple, encompasses a rich tapestry of concepts with far-reaching applications across diverse fields. It primarily refers to structures built from simpler components, and its meaning varies depending on the mathematical context. This article delves into the multifaceted nature of "composite ...
