Diketahui f(x)=2x+3 dan g(x)=4-x. pernyataan dibawah ini yang benar adalah​

(f+g)(x) = 2x+3 + 4-x = x + 7

(g+f)(x) = 4-x + 2x+3 = x + 7

(f-g)(x) = 2x+3-(4-x) = 3x -1

(g-f)(x) = 4-x -(2x+3) = -3x +1

(g.f)(x)/(f.g)(x) = (4-x)(2x+3) = 8x + 12 – 2x² -3x

= 12+5x-2x²

(fog)(x) = 2(4-x)+3

= 8-2x+3

= 11-2x

(gof)(x) = 4-(2x+3)

= 1-2x

semoga membantu
