Download Solution PDFधारणा:
- यदि f′(x) > 0 तो कहा जाता है कि फलन बढ़ता हुआ है।
- यदि f′(x) < 0 तो कहा जाता है कि फलन घटता हुआ है।
गणना:
दिया हुआ:
f(x) = x - ex
x के संबंध में अवकलन करके हमें मिलता है
⇒ f’(x) = 1 - ex
बढ़ते हुए फलन के लिए,
f'(x) > 0
⇒ 1 – ex > 0
⇒ ex < 1
⇒ ex < e0
∴ x < 0
इसलिए, x ∈ (-∞, 0)
