If f and g are functions, their sum f + g is the function given by ( f + g )(x) = f (x) + g (x). The domain of f + g consists of the numbers x that are in the domain of f and in the domain of g. If f and g are functions, their difference f - g is the function given by ( f - g )(x) = f (x) - g (x). The domain of f - g consists of the numbers x that are in the domain of f and in the domain of g.
The product fg is the function given by (fg)(x) = f(x)g(x) The domain of fg consists of the numbers x that are in the domain of f and in the domain of g. 0 ) ( , ) ( ) ( ) ( by given function the is quotient The = x g x g x f x g f g f The domain of the quotient consists of the numbers x that are in the domain of f and in the domain of g for which g(x) is NOT zero .
