Discrete Mathematics
The composition of functions is a mathematical operation that takes two functions, say f and g, and combines them into a new function, denoted as (f ∘ g)(x) = f(g(x)). This means that the output of the function g is fed as the input to the function f. Understanding this concept is crucial, as it not only emphasizes how functions can be combined to create new outputs, but it also highlights the relationships between different functions and their properties.
