tentukan invers dari x - 8 / 2 x + 4

- Fungsi Invers -

f(x) = x-8 / 2x+4
y = x-8 / 2x+4
y(2x+4) = x-8
2xy + 4y = x-8
2xy-x = -4y-8
x(2y-1) = -4y-8
x = -4y-8 / 2y-1
f-1(x) = -4x-8/2x-1

semoga membantu

y= x-8 / 2x+4
2xy+4y = x-8
2xy-x    = -8-4y
x(2y-1) = -8-4y
x = -8-4y / 2y-1

insyaAllah benar kalo gak salah
