ग्राफ \(y=3-\sqrt{x-1}\) का अधिकतम मान क्या है?
What is the maximum value of the graph \(y=3-\sqrt{x-1}\)?
Explanation opens after your attempt
C. (3)
Concept
Since \(\sqrt{x-1}\ge0\) and its least value is (0) at (x=1), \(y\le3\). In exams, for a negative square-root graph, check the starting point for maximum.
Why this answer is correct
The correct answer is C. (3). Since \(\sqrt{x-1}\ge0\) and its least value is (0) at (x=1), \(y\le3\). In exams, for a negative square-root graph, check the starting point for maximum.
Exam Tip
\(\sqrt{x-1}\ge0\) और सबसे छोटा मान (0) (x=1) पर है इसलिए \(y\le3\)। परीक्षा में ऋणात्मक वर्गमूल वाले ग्राफ का अधिकतम आरंभिक बिंदु पर देखें।
