We will be doing composition of functions. Composition of functions is done by substituting one function into another function. For example, f (g(x)) is the composite function of f (x) and g (x). The composite function f (g (x)) is read as “f of g of x”. The function g (x) is called an inner function and the function f (x) is called an outer function. Remember, we always start with the inner most parentheses.
