1)x+3/x"-9
x+3/(x+3)(x-3).disederhanaan
yang sama di coret jadi tnggal
x-3
hanya tau iti maaf kalo salah

1. f/g (x)= x - 3 / x^2 - 9
= x - 3 / (x - 3)(x + 3)
= 1 / x - 3

2. a. (g o f)(x)
= 3( 2x + 1 )^2 + 5
= 3(4x^2 + 4x + 1) + 5
= 12x^2 + 12x + 3 + 5
= 12x^2 + 12x + 8

b. (g o f)(-2)
= 12x^2 + 12x + 8
= 12 (-2)^2 + 12 (-2) + 8
= 48 - 24 + 8
= 16

3. g'(x) = - x - 3 / 2
f(x) = g' o (g o f)
= - 2x - 9 - 3 / 2
= - 2x - 12 / 2
= -x - 6


Maaf kalo kurang tepat
