Tolong buat ulangan besok yang bisa thanks
(x,y) ditranslasi T [1,-3] ➡️ (x+1 , y-3)
x' = x+1 , x'-1 = x
y' = y-3 , y'+3 = y
(y'+3) = (x'-1)² + 2(x'-1) + 1
(y'+3) = (x'²-2x'+1) + 2x'-2 + 1
y = x² – 3
b. (x,y) direfleksi x = 3 ➡️ (6-x , y)
x' = 6-x , x = -x'+6
y' = y
y' = (-x'+6)² + 2(-x+6) + 1
y' = (x'² – 12x' + 36) + (-2x+12) + 1
y = x² – 14x + 49
c. (x,y) didilatasi [O,2] ➡️ (2x , 2y)
x' = 2x , x'/2 = x
y' = 2y , y'/2 = y
y' = (x'/2)² + 2(x'/2) + 1
y' = x'²/4 + 2x'/4 + 1
y = (x² + 2x + 4)/4
semoga membantu 😉
