dik : g(x) =3x-2 f(x) = 3x+2x²-5 dit : tentukan nilai p jila (gof)(p) =-1

[tex](g \: o \: f)(x) = g(f(x)) \\ (g \: o \: f)(x) = 3(2 {x}^{2} + 3x - 5) - 2 \\ (g \: o \: f)(x)= 6 {x}^{2} + 9x - 15 - 2 \\ \\ (g \: o \: f)(p) = 6 ({p})^{2} + 9(p) - 17 = -1\\ (g \: o \: f)(p) = 6({p})^{2} + 9(p) - 16 = 0 [/tex]
