kaka aku udah ada isinya aku mau minta caranya dongg cepet yakkak pliss

Bab Fungsi Komposisi

(f o g o h)(2) = f(g(h(2)))

Cari dulu h(2)
h(2) = (2)^2 - 7(2) + 4
h(2) = 4 - 14 + 4
h(2) = -6

f(g(h(2))) = f(g(-6))

Cari nilai g(-6)
g(-6) = -6 + 3
g(-6) = -3

f(g(-6)) = f(-3)

Misalkan
x + 2 = -3
Maka
x = -3 - 2
x = -5

f(x + 2) = 3x + 5
f(-3) = 3(-5) + 5
f(-3) = -15 + 5
f(-3) = -10
