Question

Hitunglah nilai f(8)
tolong sekalian caranya, nanti saya follow.

Answer 1

Verified answer

(f^-1og^-1oh^-1) (x) = 2x  - 4
(f^-1o(g^-1oh^-1))^-1(x) = 2x-4
(g^-1oh^-1)^-1of)(x) = (x+4)/2
(hog)(f(x)) = (x+4)/2
(f(x) - 3)/(2f(x) +1) = (x+4)/2
2f(x) - 6 = 2f(x) (x+4) +( x+4)
2f(x) - 2f(x) (x+4) = 6+x+4
2f(x) ( 1- x-4) = x + 10
2f(x) (-x-3) = (x+10)
2f(x) = (x+10)/(-x-3)
f(x) = (x+10)/ (-2x-6)
f(8) = (8+10) /(-2.8 - 6) = 18/-22 = -9/11
