Find the domain of \(f(x) = \frac{x}{3 - x}, x \in R\), the set of real numbers.

  • A \({x : x \in R, x \neq 3}\)
  • B \({x : x \in R, x \neq 1}\)
  • C \({x : x \in R, x \neq 0}\)
  • D \({x : x \in R, x\neq -3}\)

The correct answer is A. \({x : x \in R, x \neq 3}\)

\(f(x) = \frac{x}{3 - x} \)

f(x) has a defined value except at x = 3 where the function is undefined.
