Final answer:
The function n(x) is defined as the product of two functions f(x) and g(x). The definition of the function n(x) is n(x) = f(x) * g(x).
Step-by-step explanation:
The function n(x) is defined as the product of two functions f(x) and g(x).
So, the definition of the function n(x) is: n(x) = f(x) * g(x).
