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, xneq -3})
Correct Answer: Option A
Explanation
(f(x) = frac{x}{3 – x} )
f(x) has a defined value except at x = 3 where the function is undefined.
