Final answer:
The domain of the function f(x) = 4(√2) - 10x + 8, where x is a real number between 0 and 20, inclusive, is [0, 20] in interval notation.
Step-by-step explanation:
The student's question concerns finding the domain of a function and expressing it in interval notation. The function, as interpreted from the provided question, appears to be a constant function of the form f(x) = 4(√2) - 10x + 8, where x is any real number between 0 and 20, inclusive. To express the domain of this function in interval notation, we recognize that x can take on any value between 0 and 20. Therefore, the domain of f in interval notation is [0, 20].
