When defining a function, you usually state what kind of numbers the domain ( x) and range ( f (x)) …The domain is usually defined for the set of real numbers that can serve as the function's input to output another real number. If you input any number less than 4, the output would be a complex number, and would not count toward the domain. The function provided in the video would be undefined for real numbers less than 4. The Codomain is actually part of the definition of the function. And The Range is the set of values that actually do come out. Example: we can define a function f (x)=2x with a domain and codomain of integers (because we say so). But by thinking about it we can see that the range (actual output values) is just the even integers. The domain is usually defined for the set of real numbers that can serve as the function's input to output another real number.
