Question

Diketahui g(x-2) = 2x + 7 dan (h o g) (x) = 4x2 + 44x + 1. Nilai h(10) ????

Answer 1

G(x-2) = 2(x-2) + 11
maka g(x) = 2x+11
h(10) berarti g(x)=2x+11=10 ===>x=-1/2
maka h(g(x))= 4x^2 + 44x + 1  dimana h(10) = h(g(-1/2))
           h(g(-1/2))= 4 (-1/2)^2  + 44 (-1/2)  + 1
                             = 1-22+1
                             =-20
Jadi h(10) = -20
