If you're seeing this message, it means we're having trouble loading external resources on our website. A function f: R → R defined by y = f (x) = c, x ∈ R,where c is a constant is called a constant function. For example: Identify the domain of the function f(x) = (x + 1) / (x - 1). Before, getting into the topic of domain and range, let’s briefly describe what a function is. Practice. Define each function’s domain and range as well. In its simplest form the domain is all the values that go into a function, and the range is all the values that come out. The domain of a function is the set of all possible inputs for the function.
