kak tolong ya tahu dikumpul hari ini... ​

Answer 1

Penjelasan dengan langkah-langkah:

g(x) = 5/(x - 2)

(fog)(x) = 2x - 3

cari invers g(x)

g(x) = 5/(x - 2)

y = 5/(x - 2)

y(x - 2) = 5

xy - 2y = 5

xy = 5 + 2y

x = (5 + 2y)/y

(fog)(x) = f(g(x))

2x - 3 = f(5/(x - 2))

f(5/(x - 2)) = 2x - 3

f(y) = 2(5 + 2y/y) - 3

f(y) = (10 + 4y)/y - 3

f(y) = (10 + 4y - 3y)/y

f(y) = (10 + y)/y

f(x) = (10 + x)/x
