Regn først ut den deriverte til $f(x)$, $f'(x)=$[[4]]

\n

Bruk nå definisjonen til den deriverte for å finne $f'(x)$

\n

(Merk: Når du trenger å skrive inn $xh$ bruk * mellom: x*h)

\n

Den deriverte til funksjonen $f(x)$ er definert ved

\n

$f'(x)=\\lim\\limits_{h\\rightarrow0}\\dfrac{f(x+h)-f(x)}{h}$

\n

\n

Først finn $f(x+h)=$[[0]]

\n

\n

videre regn ut $f(x+h)-f(x)=$[[1]]

\n

\n

Forenkle $\\dfrac{f(x+h)-f(x)}{h}$=[[2]]

\n

\n

Da $f'(x)=\\lim\\limits_{h\\rightarrow0}\\dfrac{f(x+h)-f(x)}{h}=$[[3]]
