Do you mean f%28x%29=+x%5E2%2B1%2F%28x%5E2-3x%29 or f%28x%29=+%28x%5E2%2B1%29%2F%28x%5E2-3x%29 ?
Do you mean something else?

The denominator must not be zero. In either one of the choices I asked, this means x%5E2-3x%3C%3E0
x%28x-3%29%3C%3E0
x%3C%3E0 and x%3C%3E3

The domain is all real numbers EXCLUDING 0 and +3.
