Best ResponseYou've already chosen the best response.0The domain required, if we're talking about only real numbers here, is when imputing an x into the denominator to make the denominator NOT 0. Therefore, the domain is when \[x \neq 1/3\]

Best ResponseYou've already chosen the best response.0Now what about the infinite union? If your function is \[ f(x)=\frac{x}{3x1} \] the domain is exactly \[x\neq \frac{1}{3}\]. Representing this as a union would be: \[(\infty , \frac{1}{3}) \cup (\frac{1}{3}, \infty \]

Best ResponseYou've already chosen the best response.0I forgot to close the parenthesis: \[(\infty, \frac{1}{3}) \cup (\frac{1}{3}, \infty)\]
