ग्राफ (y=-(x+4)2+9) की रेंज क्या है?
What is the range of the graph (y=-(x+4)2+9)?
Explanation opens after your attempt
A. ( \(-\infty,9] \)
Concept
The parabola opens downward and its vertex has (y=9). Hence the range is ( \(-\infty,9] \).
Why this answer is correct
The correct answer is A. ( \(-\infty,9] \). The parabola opens downward and its vertex has (y=9). Hence the range is ( \(-\infty,9] \).
Exam Tip
परवलय नीचे खुलता है और शीर्ष पर (y=9) है। इसलिए रेंज ( \(-\infty,9] \) है।
