Question

Diketahui fungsi f(x) = 4x-5 dan g(x) = √2x+1. Tentukan nilai dari (f °g)(4) dan (g°f)(2)! Tolong diberi cara mengerjakannya secara lengkap ya terima kasih :)

Answer 1

Soal kemaren gua ulangan :v

Answer 2

(fog)(4) = f(g(4))= f() = f = f(3) = 4.3 - 5 = 7
(gof)(2) = g(f(2)) = g(4.2 - 5)= g(3) = =
