Question

$x = 10$ पर $x^2 - 2$ का अवकलज ज्ञात कीजिए l

Answer 1

Answer:

Step-by-step explanation:

∵  $f (x)  = x^2-2$

∴

$f(10)=\lim_h_\rightarrow_0 \dfrac{f(10+h)-f(10)}{h}\\ \\=\lim_h_\rightarrow_0 \dfrac{[(10+h)^2-2]-[10^2-2]}{h}\\\\=\lim_h_\rightarrow_0 \dfrac{(100+20h+h^2-2)-(100-2)}{h}\\\\=\lim_h_\rightarrow_0 \dfrac{(h^2+20h+98)-(98)}{h}\\\\=\lim_h_\rightarrow_0 (h+20)\\\\=20$

$f(10)=20$

Answer 2

Step-by-step explanation:

if x=10

x²-2

= 10²- 2

= 100 - 2

= 98 Is your answer
