semoga membantu dan bermanfaat :)

Penjelasan dengan langkah-langkah:

Answer 2

8. 2[g o g [x] ] = 2.g[g(x)]

2.(g[g(x)]) = 2.(2g(x) - 1)/(6g(x)+2)

              = 2.1/2 . (2g(x) - 1)/(3g(x)+1)

2.(g[g(x)]) = (2g(x) - 1)/(3g(x)+1)

10. f(g(-4)) + 2 = g(f(2))

g(-4) = 3.(-4)+14 = 2

f(g(-4)) = f(2)

f(2) = 2²-2n

g(f(2)) = g(4-2n) = 3.(4-2n)+14

4-2n + 2 = 3(4-2n)+14

2 - 14 = 2(4-2n)

-12 = 2(4-2n)

-6 = 4-2n

-3 = 2-n

n = 5
