किस फलन के ग्राफ का परिसर ( \(-\infty,\infty\) ) है?
Which function has range ( \(-\infty,\infty\) )?
Explanation opens after your attempt
C. (f(x)=x-3)
Concept
\(x^3\) can take every real (y)-value. In exams, take the range of the cubic function as all real numbers.
Why this answer is correct
The correct answer is C. (f(x)=x-3). \(x^3\) can take every real (y)-value. In exams, take the range of the cubic function as all real numbers.
Exam Tip
\(x^3\) हर वास्तविक (y)-मान ले सकता है। परीक्षा में घन फलन का परिसर पूरे वास्तविक संख्याओं का सेट मानें।
