यदि (f(x)=\frac{1}{x}) और (g(x)=x) हों, तो ((f+g)(x)) का domain क्या है?
If (f(x)=\frac{1}{x}) and (g(x)=x), what is the domain of ((f+g)(x))?
Explanation opens after your attempt
Correct Answer
A. \(\mathbb{R}-{0}\)
Concept
In \(\frac{1}{x}\), the denominator becomes zero at (x=0). Therefore, the domain of the sum is \(\mathbb{R}-{0}\).
Why this answer is correct
The correct answer is A. \(\mathbb{R}-{0}\). In \(\frac{1}{x}\), the denominator becomes zero at (x=0). Therefore, the domain of the sum is \(\mathbb{R}-{0}\).
Exam Tip
\(\frac{1}{x}\) में (x=0) पर denominator शून्य हो जाता है। इसलिए sum का domain \(\mathbb{R}-{0}\) है।
