Jawaban:
F
Penjelasan dengan langkah-langkah:
(g o f)(x) = 4x² + 4x + 3 , g(x) = x² – 1
[f²(x)] – 1 = 4x² + 4x + 3
f²(x) = 4x² + 4x + 3 + 1
f(x) = √(4x² + 4x + 4)
f(x) = √[(2x + 2)² - 4x]
f(x + 1) = √[(2[x – 1] + 2)² – 4(x – 1)]
f(x) = √[(2x – 2 + 2)² –4x + 1]
f(x) = √(4x² – 4x + 1)
f(x) = √(2x – 1)²
