The domains of both f(x) and g(x) must be (–∞, ∞).
We have given that,
The function h(x) shown is the result of adding two functions, f(x) and g(x).
We have to determine
The statement could be used to describe the functions.
What is the function?
A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
The domain of the function is the set of point at which function is defined.
Therefore, The domains of both f(x) and g(x) must be (–∞, ∞).
