परिभाषा की सहायता से निम्न फलन के विकलित प्राप्त कीजिए ।

प्रश्न 1.
f(x) = 2x + 3
उत्तर :
यहाँ f(x) = 2x +3 ∴ f(x + h) = x + h
f(x) \(\lim _{h \rightarrow 0} \frac{f(x+h)-f(x)}{h}\) (x + h – t रखने पर h → 0 तब t → x)
\(\lim _{t \rightarrow x} \frac{2 t^n-x^n}{t-x}\) (∵ x + h = t)
= 2 × (1)2 – 1 = 2 × 1 = 2Φ f(x) = 2x + 3 हो, तो f’ (x) = 2

प्रश्न 2.
f(x)= x2
उत्तर :
यहाँ f(x)= x2 ∴ f(x + h) = (x + h)2

= 2x2 – 1 = 2(x)1 = 2x अब यदि f(x) = x2 = 2x

प्रश्न 3.
f(x) = x7
उत्तर :
यहाँ f(x) = x7 ∴ f(x + h) = (x + h)7

= 7x7 – 1 = 7x6 f(x)= x7 = 7x6
