f(x)=2x^+3x+1 f(x-2)

jawab

f(x)= 2x² + 3x + 1

f(x-2) = 2 (x -2)² + 3(x -2) + 1
f(x-2) = 2 (x² - 4x + 4) + 3x - 6 + 1
f(x-2)= 2x² -8x  + 8+ 3x - 5
f(x-2) = 2x² - 5x + 3

dik : f(x) = 2x²+3x+1
f(x-2)

jawab :
f(x) = 2x²+3x+1
f(x) = 2(x-2)² + 3(x-2) + 1
= 2(x²-4x+4) + 3x - 6 + 1
= 2x² -8x +8 +3x -5
= 2x² -8x +3x +8-5
= 2x² - 5x + 3

semoga membantu.....
