Function Composition
Function composition refers to the process of combining two or more functions to create a new function. This new function is formed by applying one function to the output of another function. In mathematical terms, if f(x) and g(x) are two functions, the composition of f and g is denoted as (f ∘ g)(x) and is defined as f(g(x)). This allows for the chaining of functions together to perform more complex operations.
