फलन (f(x)=\frac{2}{x+1}) का प्रांत क्या है?
What is the domain of (f(x)=\frac{2}{x+1})?
Explanation opens after your attempt
A. \(\mathbb{R}-{-1}\)
Concept
The denominator is (x+1), so it becomes (0) at (x=-1). This value is removed from the domain.
Why this answer is correct
The correct answer is A. \(\mathbb{R}-{-1}\). The denominator is (x+1), so it becomes (0) at (x=-1). This value is removed from the domain.
Exam Tip
हर (x+1) है, इसलिए (x=-1) पर हर (0) हो जाता है। इस मान को प्रांत से हटाते हैं।
