यदि (f(x)=\frac{1}{x-a}) का प्रांत \(\mathbb{R}\setminus{5}\) है, तो (a) क्या है?

If the domain of (f(x)=\frac{1}{x-a}) is \(\mathbb{R}\setminus{5}\), what is (a)?

Explanation opens after your attempt
Correct Answer

A. (5)

Step 1

Concept

The denominator becomes zero at (x=a), so that value is removed. The removed value is (5), hence (a=5).

Step 2

Why this answer is correct

The correct answer is A. (5). The denominator becomes zero at (x=a), so that value is removed. The removed value is (5), hence (a=5).

Step 3

Exam Tip

हर शून्य होने पर (x=a) हटता है। दिए गए हटे हुए मान से (a=5) है।
