pasangan koordinat pada grafik f(x) =x+2

Bab Persamaan Garis
Matematika SMP Kelas VIII

f(x) = x + 2
Misal, x = { -2, -1, 0, 1, 2 }

f(-2) = -2 + 2
f(-2) = 0
(-2, 0)

f(-1) = -1 + 2
f(-1) = 1
(-1, 1)

f(0) = 0 + 2
f(0) = 2
(0, 2)

f(1) = 1 + 2
f(1) = 3
(1, 3)

f(2) = 2 + 2
f(2) = 4
(2, 4)

Pasangan koordinat = { (-2, 0), (-1, 1), (0, 2), (1, 3), (2, 4) }
