INVERS FUNGSI

Fungsi Invers adalah suatu fungsi yang berkebalikan dari fungsi asalnya.

Pada umumnya, invers fungsi dinyatakan dengan lambang f^-1(x)

INVERS FUNGSI

Suatu proses alur mundur merupakan prosedur balikan/invers.

Jika fungsi f : A → B ditentukan dengan aturan y = f(x),

maka invers dari fungsi f dapat dituliskan menjadi f^{- –1}: B → A

dengan aturan x = f^{- –1}(y).

Tidak semua invers fungsi merupakan fungsi invers
