Rumus-rumus Fungsi dan Fungsi Invers

FUNGSI ASAL
FUNGSI INVERS
f(x) = ax+b ; a ¹ 0 f-1(x) = (x-b)/a ; a ¹ 0
f(x) = (ax+b)/(cx+d) ; x ¹ -d/c f-1(x) = (-dx+b)/(cx-a) ; x ¹ a/c
f(x) = ax² + bx + c ; a ¹ 0 f-1(x) = (-b+Ö(b²-4a(c-x))/2a ; a ¹ 0
f(x) = a log cx ; a > 0 ¹ 1 ; cx>0 f-1(x) = ax/c ; c ¹ 0
f(x) = acx ; a > 0 ¹ 1 f-1(x) = alog x1/c = 1/c alog x ; c¹0

Keterangan : fungsi invers ini ada, jika syarat-syaratnya terpenuhi

Fungsi kuadrat secara umum tidak mempunyai invers, tetapi dapat mempunyai invers jika daerah definisinya dibatasi.
