ग्राफ \(y=x^2+1\) (x)-अक्ष को कितनी बार काटता है?
How many times does the graph \(y=x^2+1\) cut the (x)-axis?
Explanation opens after your attempt
A. (0) बार(0) times
Concept
\(x^2+1\) is always at least (1), so (y=0) is impossible. In exams, use the minimum value to check (x)-intercepts.
Why this answer is correct
The correct answer is A. (0) बार / (0) times. \(x^2+1\) is always at least (1), so (y=0) is impossible. In exams, use the minimum value to check (x)-intercepts.
Exam Tip
\(x^2+1\) हमेशा (1) या उससे बड़ा है इसलिए (y=0) नहीं हो सकता। परीक्षा में न्यूनतम मान से (x)-अवरोध जांचें।
