tolong dong, itu x nya diganti (x-2) ko gabisa y? atau emg caranya ga gitu ?

h(x) = 2x² -3x +1
h(x-2) =2(x-2)² -3(x-2) +1
h(x-2) =2(x²-4x+4) -3x+6+1
h(x-2) = 2x²-8x + 8 -3x +7
h(x-2) = 2x² -11x + 15

mungkin kurang ketelitian 
semoga membantu

h(x) = 2x²-3x+1

h(x-2) =2(x-2)²-3(x-2)+1
=2(x²-4x+4)-3(x-2)+1
=2x²-8x+8-3x+6+1
= 2x²-11x+15

jawabannya D
