What type of change is represented by the function \(y=-3x+12\)?फलन \(y=-3x+12\) किस प्रकार के परिवर्तन को दर्शाता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: A linear decay relation with a negative slopeऋणात्मक ढाल वाला रैखिक ह्रास संबंध
The coefficient of \(x\) is \(-3\), so \(y\) decreases as \(x\) increases; this is linear decay. A positive slope would indicate growth. Exam tip: the coefficient of \(x\) is the slope.\(x\) का गुणांक \(-3\) है, इसलिए \(x\) बढ़ने पर \(y\) घटता है; अतः यह रैखिक ह्रास है। धनात्मक ढाल वृद्धि दिखाती है। परीक्षा टिप: \(x\) का गुणांक ढाल होता है।
