Kunci Jawaban Matematika Kelas 9 Halaman 87 dan 88 Isi Tabel dan Menggambar Grafik Fungsi Kuadrat

x = 0
y = (0)⊃2; - 2(0)
y = 0

(x,y) = (0,0)

x = 1
y = (1)⊃2; - 2(1)
y = -1

(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 = -x⊃2; + 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)

x = 0
y = -(0)⊃2; + 2(0)
y = 0

(x,y) = (0,0)
