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
Correct Answer

A. \(y\le3\)

Step 1

Concept

Since \(-x^2\le0\), \(3-x^2\le3\). A downward-opening parabola has its maximum at the vertex.

Step 2

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.

Step 3

Exam Tip

\(-x^2\le0\), इसलिए \(3-x^2\le3\)। नीचे खुलने वाले परवलय में शीर्ष अधिकतम देता है।
