Determine if domain and range are a function
WebMar 29, 2024 · The domain and range of a function are the components of a function. The domain is the set of all the input values of a function and the range is the possible … 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. 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.
