Fungsi Invers dari fungsi tsb adalah

$f^{-1} (x) = \frac {2x + 4}{5x - 3}$

PEMBAHASAN

$f(x) = \frac {3x+4}{5x-2}$

CARA 1

misalkan, f(x) = y

maka, fungsi invers

$f(x) = \frac {3x+4}{5x-2}$

$y = \frac {3x+4}{5x-2}$

$5xy - 2y = 3x + 4$

$5xy - 3x = 4 + 2y$

$x(5y - 3) = 4 + 2y$

$x = \frac {4 + 2y}{5y - 3}$

• ganti variabel menjadi variabel awal

$f^{-1} (x) = \frac {4 + 2x}{5x - 3}$

$f^{-1} (x) = \frac {2x + 4}{5x - 3}$

CARA 2 : CARA CEPAT

Jika $f(x) = \frac {ax+b}{cx+d}$

maka, $f^{-1} (x) = \frac {-dx+b}{cx - a}$

maka, $f(x) = \frac {3x+4}{5x-2}$

a = 3

b = 4

c = 5

d = -2

inversnya,

$f^{-1} (x) = \frac {-dx+b}{cx - a}$

$f^{-1} (x) = \frac {2x + 4}{5x - 3}$
