Find the domain of \(f(x) = \frac{x}{3 - x}, x \in R\), the set of real numbers.
\({x : x \in R, x \neq 3}\)
\({x : x \in R, x \neq 1}\)
\({x : x \in R, x \neq 0}\)
\({x : x \in R, x\neq -3}\)
Vysvětlení
\(f(x) = \frac{x}{3 - x} \)
f(x) has a defined value except at x = 3 where the function is undefined.
