Diketahui g(x) = 6 – 11x dan f(x) = 3x – 9. tentukan (fog)–¹ (x)​

Bentar ya kak …di tunggu

Jawab:

Penjelasan dengan langkah-langkah:

(fog)–¹ (x)​ = ?

(fog)(x) = 3 (6-11x) – 9

           = 18 – 33x – 9

           = -33x + 9

(fog)–¹ (x)​ = -33x + 9

            y = -33x + 9

        33x = -y + 9

           x = (-y +9) / 33

(fog)–¹ (x) = (-x +9) / 33
