Which statement is correct for f(x)=1/(x^2-4)?

Answer and explanation

Correct answer: The domain is R\{-2,2}

The governing concept is the domain restriction of a rational function: its denominator must not be zero. Here x^2-4=(x-2)(x+2). Setting the denominator equal to zero gives x=2 or x=-2. These two inputs are excluded because division by zero is undefined. Every other real number makes the denominator non-zero, so the domain is R\{-2,2}, exactly as stated in option A. Option B removes 0 even though the denominator at 0 is -4 and the function is defined there. Option C incorrectly retains only the interval between the zeros, while option D excludes the interval and incorrectly includes the endpoints, where the denominator is zero. Thus A is the only correct statement.
