Bantuu jawabb dung tolong acuuu bsok mau dikumpul:')
Jika f(x) = 2x + 3 dan (fog)(x) = 2x² + 8x + 3 , maka (gof)(2)=.…???
f(x) = 2x + 3
(fog)(x) = 2x² + 8x + 3
f {g(x) } = 2x² + 8x + 3
2. g(x) + 3 = 2x² + 8x + 3
2 g(x) = 2x² + 8x
g(x) = x² + 4x
gof(2) = g { f(2)} = g ( 2 .2 + 3 )
gof(2) = g (7)
gof(2) = 7² + 4(7) = 77
