फलन (f(x)=\frac{1}{x-9}+4) की रेंज क्या है?
What is the range of (f(x)=\frac{1}{x-9}+4)?
Explanation opens after your attempt
Correct Answer
A. \(\mathbb{R}\setminus{4}\)
Concept
\(\frac{1}{x-9}\) is never (0), so output (4) cannot occur. In exams identify the excluded range value after a vertical shift.
Why this answer is correct
The correct answer is A. \(\mathbb{R}\setminus{4}\). \(\frac{1}{x-9}\) is never (0), so output (4) cannot occur. In exams identify the excluded range value after a vertical shift.
Exam Tip
\(\frac{1}{x-9}\) कभी (0) नहीं होता, इसलिए (4) output नहीं बन सकता। परीक्षा में vertical shift से excluded range value पहचानें।
