Kunci Jawaban Matematika Kelas 9 Halaman 87, Melengkapi Tabel Fungsi Kuadrat

(x,y) = (1,-1)

x = 2
y = (2)² - 2(2)
y = 0

(x,y) = (2,0)

x = 3
y = (3)² - 2(3)
y = 3

(x,y) = (3,3)

Tabel C, diketahui y = -x² + 2x

x = -2
y = -(-2)² + 2(-2)
y = -8

(x,y) = (-2,-8)

x = -1
y = -(-1)² + 2(-1)
y = -3

(x,y) = (-1,-3)
