Question

Jika f(x) = x²-3x+1, maka f(x-2)=
pilgan

a.x²-7x+15. c.x²-7x+13
b.x²-7x+14. d.x²-7x+12

e.x²-7x+11

pke cara ya

Answer 1

F(x) = x²-3x+1, maka f(x-2)
f(x-2) = (x-2)² -3(x-2)² +1
f(x-2) = x² -4x +4 -3(x² -4x +4) +1
f(x-2) = x² -4x +4 -3x² +12x -12 +1
f(x-2) = -2x² +8x -7
f(x-2) = 2x² -8x +7
f(x-2) = x²-4x +7/2

tp ga ada dstu ya? maaf y klo slh hitung

Answer 2

F(x) = x²-3x+1

ganti semua x pada fungsi dengan x-2 maka didapat
f(x-2) = (x-2)²-3(x-2)+1
f(x-2) = (x²-4x+4)-3x+6+1
f(x-2) = x²-4x-3x+4+6+1
f(x-2) = x²-7x+11
