फलन (f(x)=\frac{x+2}{x-2-4}) का डोमेन क्या है?
What is the domain of (f(x)=\frac{x+2}{x-2-4})?
Explanation opens after your attempt
Correct Answer
A. \(\mathbb{R}\setminus{-2,2}\)
Concept
The original denominator is (x-2-4=(x-2)(x+2)), so \(x\ne -2,2\). In exams remove zeros of the original denominator before cancellation.
Why this answer is correct
The correct answer is A. \(\mathbb{R}\setminus{-2,2}\). The original denominator is (x-2-4=(x-2)(x+2)), so \(x\ne -2,2\). In exams remove zeros of the original denominator before cancellation.
Exam Tip
मूल हर (x-2-4=(x-2)(x+2)) है, इसलिए \(x\ne -2,2\)। परीक्षा में काटने से पहले मूल हर के शून्य हटाएं।
