ग्राफ \(y=3-x^2\) का परिसर क्या है?
What is the range of the graph \(y=3-x^2\)?
Explanation opens after your attempt
A. \(y\le3\)
Concept
Since \(-x^2\le0\), \(3-x^2\le3\). A downward-opening parabola has its maximum at the vertex.
Why this answer is correct
The correct answer is A. \(y\le3\). Since \(-x^2\le0\), \(3-x^2\le3\). A downward-opening parabola has its maximum at the vertex.
Exam Tip
\(-x^2\le0\), इसलिए \(3-x^2\le3\)। नीचे खुलने वाले परवलय में शीर्ष अधिकतम देता है।
