WebFor each number that you want to know whether or not it is in the domain, you plug in that number for x, and see if the answer makes sense. I'm going to look at the function x+5/x-3. If I plug in 0, I get 0+5/0-3, which turns into -5/3. That's a real number, so 0 is in the domain of the function. If I plug in 3, I get 3+5/3-3, which turns into 8/0. intel b560 chipset specsWebchosen x-value is said to belong to the domain of f. If there is a requirement that a y-value produced by a function must be a real number, the following conditions are commonly checked: 1. Denominators cannot equal 0. 2.
