Diketahui f(x) 2x-5 /3x-7 buktikan fof' = x
![]()
Jawaban:
Ok
Penjelasan dengan langkah-langkah:
f(x) = 2x - 5
g(x) = 3x - 7
maka
(fog)(x)
= f (g(x))
= f (3x - 7)
= 2 (3x-7) - 5 = 6x - 14 - 5
= 6x - 19
atau
f(x) = 2x - 5 g(x) = 3x - 7
(fog)(x) = f(g(x))
(fog)(x) = 2(g(x)) - 5
(fog)(x) = 2(3x - 7) - 5
(fog)(x) = 6x - 19
(fog)(x) = 6x - 19
