ग्राफ (y=-3|x-2|+9) का अधिकतम मान और उसका (x)-मान क्या है?
What are the maximum value and its (x)-value for the graph (y=-3|x-2|+9)?
Explanation opens after your attempt
A. अधिकतम (9) जब (x=2)maximum (9) when (x=2)
Concept
The minimum of (|x-2|) is (0) at (x=2), so (y=9) is maximum. In exams, a modulus graph with a negative multiplier has maximum at the vertex.
Why this answer is correct
The correct answer is A. अधिकतम (9) जब (x=2) / maximum (9) when (x=2). The minimum of (|x-2|) is (0) at (x=2), so (y=9) is maximum. In exams, a modulus graph with a negative multiplier has maximum at the vertex.
Exam Tip
(|x-2|) का न्यूनतम (0) (x=2) पर है इसलिए (y=9) अधिकतम है। परीक्षा में ऋणात्मक गुणक वाले मापांक में शीर्ष अधिकतम होता है।
