jika f(x) = 2x+5 dan g(x) = x-3/ x+4 . maka nilai (fog) -¹(1) yaitu? di jawab yaaa beserta dengan cara kerjanya. plisss

(fog)(x) = 2(x - 3)/(x + 4) + 5

(fog)^-1 (2(x - 3)/(x + 4) + 5) = x

(fog)^-1 (1) = x

2(x - 3)/(x + 4) + 5 = 1
2(x - 3)/(x + 4) = 1 - 5
(x - 3)/(x + 4) = -4/2
x - 3 = -2(x + 4)
x - 3 = -2x - 8
x + 2x = 3 - 8
3x = -5
x = -5/3

(fog)^-1 (1) = x = -5/3
