Fungsi (g o f) (x) = 18x²+24x+2 serta fungsi g(x) = 2x–6. Tentukan rumus dari f (x) !

f(x) = 9x² + 12x + 4
f(x) = 10x² + 20x + 5
f(x) = 7x² + 14x + 1
f(x) = 8x² + 10x + 3

Terdapat fungsi f (x) = x+2 beserta g (x) = x²–4. Tentukan fungsi dari (f/g) (x) !

(f/g)(x) = (x - 2) / (x² + 4)
(f/g)(x) = (x + 2) / (x² + 4)
(f/g)(x) = (x + 2) * (x² - 4)
(f/g)(x) = (x + 2) / (x² - 4)

(f/g)(x) = (x + 2) * (x² + 4)
