यदि (f(x)=\frac{2x+1}{x-3}), तो (f) का प्रांत क्या है?
If (f(x)=\frac{2x+1}{x-3}), what is the domain of (f)?
Explanation opens after your attempt
Correct Answer
A. \(\mathbb{R}-{3}\)
Concept
The denominator \(x-3\ne 0\), so \(x\ne 3\). For rational functions, check the denominator condition first.
Why this answer is correct
The correct answer is A. \(\mathbb{R}-{3}\). The denominator \(x-3\ne 0\), so \(x\ne 3\). For rational functions, check the denominator condition first.
Exam Tip
हर \(x-3\ne 0\), इसलिए \(x\ne 3\)। रैशनल फलन में हर की शर्त सबसे पहले देखें।
