# Multiplication of Functions

## Multiplication of Functions

Binary operation that associates every ordered pair (f, g) of functions, defined on a set E to a set F, with a new function written as fg and called the product of these functions.

To obtain the value of the product of two functions f and g with a variable x, the images f(x) and g(x) are multiplied: (f • g)(x) = f(x) × g(x).
