F(x)=4x+2 g(x) =3x-1 tentukan : 1.fog(-2) 2.gof(0) 3.gog(1/3)

- Fungsi -

*Cari fog(x)
(fog)(x) = 4(3x-3) + 2
(fog)(x) = 12x-12+2
(fog)(x) = 12x-10
maka,
(fog)(-2) = 12(-2) - 10 = -24-10 = -34

*Cari gof(x)
(gof)(x) = 3(4x+2) - 1
(gof)(x) = 12x+6-1
(gof)(x) = 12x+5
maka,
(gof)(0) = 12(0) + 5 = 5

*Cari gog(x)
(gog)(x) = 3(3x-1) - 1
(gog)(x) = 9x-3-1
(gog)(x) = 9x-4
maka,
(gog)(1/3) = 9(1/3) - 4 = 3-4 = -1
