diketahui f(x)= x-1/2x+3 dan g(x) = x/x-5, maka (g○f)(x)=... a. 5/5x-5 b. x-1/x-5 c. x-5/2x+5 d. x/2x+3 e. x-1/-9x-16

langsung aja yy

(gof)(x) = g{f(x)}

•••••••• = f(x) / f(x) - 5

•••••••• = x - 1 / 2x + 3 : x-1/2x+3 - 5

•••••••• = x-1/2x+3 : x-1-10x-15 / 2x+3

•••••••• = x - 1 / 2x + 3 : -9x-16 / 2x+3

•••••••• = x - 1 / 2x + 3 × 2x+3 / -9x - 16

•••••••• = x - 1 / -9x - 16

jawabannya E

semoga berguna +_+
