कौन सा फलन हर वास्तविक (x) पर परिभाषित है?
Which function is defined for every real (x)?
Explanation opens after your attempt
Correct Answer
C. (f(x)=x-2+8)
Concept
The polynomial \(x^2+8\) is defined for every real (x). In exams polynomial functions usually have domain \(\mathbb{R}\).
Why this answer is correct
The correct answer is C. (f(x)=x-2+8). The polynomial \(x^2+8\) is defined for every real (x). In exams polynomial functions usually have domain \(\mathbb{R}\).
Exam Tip
बहुपद \(x^2+8\) हर वास्तविक (x) के लिए परिभाषित है। परीक्षा में polynomial functions का डोमेन सामान्यतः \(\mathbb{R}\) होता है।
