फलन $4 \sqrt{x} - 2$ का अवकलज ज्ञात कीजिए। (मान लीजिए कि $a, b, c, d, p, q, r, s$ निश्चित शून्येतर स्थिरांक हैं और $m, n$ पूर्णांक हैं।)
(N/A) माना $f(x) = 4 \sqrt{x} - 2$ है।
$f'(x) = \frac{d}{dx}(4 \sqrt{x} - 2)$
$= \frac{d}{dx}(4 \sqrt{x}) - \frac{d}{dx}(2)$
$= 4 \frac{d}{dx}(x^{1/2}) - 0$
$= 4 \left( \frac{1}{2} x^{1/2 - 1} \right)$
$= 2 x^{-1/2} = \frac{2}{\sqrt{x}}$.
$f'(x) = \frac{d}{dx}(4 \sqrt{x} - 2)$
$= \frac{d}{dx}(4 \sqrt{x}) - \frac{d}{dx}(2)$
$= 4 \frac{d}{dx}(x^{1/2}) - 0$
$= 4 \left( \frac{1}{2} x^{1/2 - 1} \right)$
$= 2 x^{-1/2} = \frac{2}{\sqrt{x}}$.
