Detailed Solution
Download Solution PDFअवधारणा:
किसी फलन y = f(x) के लिए:
- स्थानीय उच्चिष्ट या निम्निष्ट के बिंदुओं पर, f'(x) = 0
- उन क्षेत्रों में जहाँ f(x) बढ़ रहा है, f'(x) > 0
- उन क्षेत्रों में जहां f(x) घट रहा है, f'(x) < 0
गणना:
फलन f(x) = x2 - 2x के निरंतर वर्धमान के लिए, f'(x) > 0
फलन f(x) = x2 − 2x के निरंतर ह्रासमान होने के लिए, f'(x) < 0।
⇒ f'(x) = 2x - 2 < 0
⇒ x < 1
⇒ x ∈ (−∞, 1)
