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
Correct Answer

A. ( \(-\infty,9] \)

Step 1

Concept

The parabola opens downward and its vertex has (y=9). Hence the range is ( \(-\infty,9] \).

Step 2

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 ( \(-\infty,9] \).

Step 3

Exam Tip

परवलय नीचे खुलता है और शीर्ष पर (y=9) है। इसलिए रेंज ( \(-\infty,9] \) है।
