Tolong bantu ya... jgn lupa pakai cara Thx~ <3<3

Fungsi Invers n' KOmposisi

12][
f(x) = (ax + b)/(cx + d)

f'(x) = (-dx + b)/(cx - a)

•••
f(x) = (x - 1)/(2x + 4)
f^-1 (x) = (-4x - 1)/(2x - 1) ✔

13][
f(x) = (x + 1)/(2x - 1)
f^-1 (x) = (x + 1)/(2x - 1) ✔

14][
f(x) = 2x - 1
g(x) = x² + 1
g(-3) = (-3)² + 1 = 9 + 1 = 10

(fog)(-3)
= f(g(-3))
= f(10)
= 2.10 - 1
= 20 - 1
= 19
