Question

Diketahui f-¹,g-¹, dan h-¹ berturut-turut menyatakan invers fungsi f, g, dan h. jika (f-¹•g-¹•h-¹)(x) =2x-4 dan (h•g) (x) =x-3/2x+1 , x=/ 1/2, nilai f(8)=...

Answer 1

(f-¹•g-¹•h-¹)(x) = 2x-4
   (hogof)⁻¹(x) = 2x-4
     (hogof)(x) = (x+4)/2
     (hogof)(8) = (8+4)/2
    (h(g(f(8)))) = 6

f(8) = (hog)⁻¹(6)
f(8) = -(x+3)/(2x-1)
f(8) = -(6+3)/(2.6-1)
f(8) = -9/11
