Question

Tolong jawab ya pakai cara soalnya bntr lagi dikumpulin!​

Answer 1

Jawab:

f(x) = 2x, g(x) = 2+x

maka (fOg)^-1(x)=

 => (f(g(x))^-1(x)=0

=> (f(2+x))^-1(x)=0

=> f(2+x) =2(2+x)

=> f(x) =4+2x

=> maka f(x)^-1= (x-4)÷2

Penjelasan dengan langkah-langkah:

Answer 2

f(x) = 2x

f^-1(x) = x/2

g(x) = 2+x

g^-1(x) = x-2

(fog)^-1(x) = g^-1(x) o f^-1(x) = g^-1(x/2) = (x/2) -2 = (x-4)/2
