Question

Diketahui : f(x)=2x, g(x)=x+1, h(x)=x^3
Ditanyakan : (hogof)(x)

Answer 1

(hogof)(x)
=(hog(2x))
=(h(2x+1))
=(2x+1)pngkt 3
=(2x+1)(2x+1)(2x+1)
= (4xkuadrat +2x + 2x +1)(2x+1)
=(4xkuadrat + 4x + 1)(2x+1)
= 8xpngt3 + 4xkuadrat + 8xkuadrat + 4x + 2x + 2
= 8xpngkt3 + 12xkuadrat + 6x +2

Answer 2

F(x)=2x
g(x)=x+1
h(x)=x^3
(hogof) (x) = hog(2x)
                = h(2x+1)
                = (2x+1)^3
