y = x2(pangkat2)-2x+1 y=-x+3

y = x² - 2x + 1
y = -x + 3

Jawab :
x² - 2x + x + 1 - 3
x² - x - 2

Terimakasi, semoga membantu.

X^2-2x+1 = -x+3
X^2-x-2 = 0
( x - 2 ) ( x + 1 ) = 0
X = 2 X = -1

X = 2 >>> y = (2)^2 -2(2) + 1 = 4-4+1 = 1 (2,1)
X = -1 >>> y = (1)^2 -2(-1) + 1 = 1+2+1 = 4
(-1,4)

Jadi jawabannya e❤️
