Komposisi Invers

f(x) = x² + 8x + 15

g(x) = x + 1

(fog)(x) = (x + 1)² + 8(x + 1) + 15

y = x² + 10x + 24

y = (x + 5)² – 1

x + 5 = ± √(y + 1)

x = -5 ± √(y + 1)

(fog)^-1 (x) = -5 ± √(x + 1)

x ≥ -1

••

(gof)(x) = x² + 8x + 15 + 1

y = (x + 4)²

x + 4 = ±√y

x = -4 ± √y

(gof)^-1 (x) = -4 ± √x

x ≥ 0
