Which function has range \(\mathbb{R}\setminus{2}\)?
Explanation opens after your attempt
Correct Answer
A. (f(x)=\frac{1}{x}+2)
Concept
\(\frac{1}{x}\) is never (0), so the output cannot be (2). In exams identify the vertical shift of a reciprocal.
Why this answer is correct
The correct answer is A. (f(x)=\frac{1}{x}+2). \(\frac{1}{x}\) is never (0), so the output cannot be (2). In exams identify the vertical shift of a reciprocal.
Exam Tip
\(\frac{1}{x}\) कभी (0) नहीं होता, इसलिए (2) आउटपुट नहीं बनता। परीक्षा में reciprocal के vertical shift को पहचानें।
