यदि (f(x)=x-2-4) और (g(x)=x-2) हैं, तो \(\frac{f}{g}\) का वास्तविक प्रांत क्या होगा?
If (f(x)=x-2-4) and (g(x)=x-2), what is the real domain of \(\frac{f}{g}\)?
Explanation opens after your attempt
B. \(\mathbb{R}\setminus{2}\)
Concept
In a quotient, the denominator (g(x)) must not be zero, so (x=2) is excluded. In exams, check the domain before simplifying.
Why this answer is correct
The correct answer is B. \(\mathbb{R}\setminus{2}\). In a quotient, the denominator (g(x)) must not be zero, so (x=2) is excluded. In exams, check the domain before simplifying.
Exam Tip
भागफल में हर (g(x)) शून्य नहीं होना चाहिए, इसलिए (x=2) हटेगा। परीक्षा में सरलीकरण से पहले प्रांत जांचें।
