Jawaban:
(f o g)-¹(16) = 0
Penjelasan dengan langkah-langkah:
FUNGSI INVERS KOMPOSISI
[tex] {f}^{ - 1} (x) = \frac{x - 1}{5} \\ f(x) = 5x + 1 \\ g(x) = 3 - 2x \\ (fog)(x) = 5(3 - 2x) + 1 \\ (fog)(x) = 16 - 10x \\ {(fog)}^{ - 1} (x) = \frac{16 - x}{10} \\ {(fog)}^{ - 1} (16) = \frac{16 - 16}{10} \\ {(fog)}^{ - 1} (16) = \frac{0}{10} \\ {(fog)}^{ - 1} (16) = 0[/tex]
