Soal 01

SIMAK UI 2019 Matematika Dasar 521

Jika $f$ dan $g$ adalah fungsi yang dapat diturunkan di $R$ sehingga

${\displaystyle \underset{h\to 0}{lim}{\displaystyle \frac{f(x+h)(g(x)-g(x+h))}{(k^2-1)h}}={\displaystyle \frac{x^2-1}{1+k}}}$, dan

${\displaystyle \underset{h\to 0}{lim}{\displaystyle \frac{g(x)(f(x)-f(x+h))}{(k^2-1)h}}={\displaystyle \frac{x^2-1}{1-k}}}$ untuk $k>1$,

maka ...

(1)   $(fg{)}^{\prime }(0)=2$

(2)   $(fg{)}^{\prime }(c)=2(x^2-1)$

(3)   $(fg{)}^{\prime }(0)=2(1-k^2)$

(4)   $(fg{)}^{\prime }(1)=0$
