Step #5: Click "CALCULATE" button. The function must work for all values we give it, so it is up to us to make sure we get the domain correct! Domain of a function is the set of all possible input values for which the function is valid. To calculate the domain of the function, you must first evaluate the terms within the equation. Let’s examine these types of functions and how to calculate their domain. Example: at x=2 we meet: an open dot at y=1 (so it does not include x=2), and a solid dot at y=2 (which does include x=2) so the answer is y=2. It has been easy so far, but now we must consider the Domains of the functions. The domain is the set of input values of X, whereas the range is the set of output values of Y. Any number should work, and will give you a final answer between −1 and 1.) Example 1: Find the domain of the function 4 x/ [(x- 2) (x- 3). Example: Determine whether the function is even or odd: $ f(x) = x^2 $ (square function) in $ \mathbb{R} $, the calculation is $ f(-x) = (-x)^2 = x^2 = f(x) $, so the square function $ f(x) $ is even.
