यदि (f(x)=\frac{3x+2}{x-1}), तो (f) का प्रांत क्या होगा?
If (f(x)=\frac{3x+2}{x-1}), what is the domain of (f)?
Explanation opens after your attempt
B. \(\mathbb{R}-{1}\)
Concept
The denominator is (x-1).
Why this answer is correct
The denominator cannot be zero, so \(x-1\neq 0\), meaning \(x\neq 1\).
Exam Tip
The domain includes only those real numbers for which the function is defined. चरण 1: भिन्न में हर (x-1) है। चरण 2: हर शून्य नहीं हो सकता, इसलिए \(x-1\neq 0\), अर्थात \(x\neq 1\)। चरण 3: प्रांत में वही वास्तविक संख्याएँ रखें जिन पर फलन परिभाषित हो।
