Which statement is correct for (f(x)=\frac{1}{x-2-4})?
Explanation opens after your attempt
Correct Answer
A. डोमेन \(\mathbb{R}\setminus{-2,2}\) हैDomain is \(\mathbb{R}\setminus{-2,2}\)
Concept
The denominator \(x^2-4\) becomes (0) when (x=-2) or (x=2). In exams remove zero values of the denominator.
Why this answer is correct
The correct answer is A. डोमेन \(\mathbb{R}\setminus{-2,2}\) है / Domain is \(\mathbb{R}\setminus{-2,2}\). The denominator \(x^2-4\) becomes (0) when (x=-2) or (x=2). In exams remove zero values of the denominator.
Exam Tip
हर \(x^2-4\) तब (0) होगा जब (x=-2) या (x=2)। परीक्षा में denominator की zero values हटाएं।
