SOAL MENANTANG PART 5!! AYO BURUAN MASUK DAN KERJAKAN SOALNYA GUYS!!

(f o g)(x) = f(g(x))
= f(x + 1)
= 2(x + 1)^2 - 3(x + 1)
= 2(x^2 + 2x + 1) - 3x - 3
= 2x^2 + 4x + 2 - 3x - 3
= 2x^2 + x - 1
Jawaban: B

F(x) = 2x^2 - 3x
G(x) = x+1

FoG(x) = 2(x+1)^2 - 3(x+1)
= 2(x^2 + 2x + 1) - 3x - 3
= 2x^2 + 4x + 2 - 3x - 3
= 2x^2 + x - 1
