f(x) = |x-1| TIDAK KONTINU di x = 1
Pembahasan :
Cari disekitar x = 1
y = | x -1 |
x = -3 , y = |-3-1| = 4 ; (-3,4)
x = -2, y = |-2-1| = 3 ; (-2, 3)
x = -1, y = |-1-1| = 2 ; (-1, 2)
x = 0, y = |0-1| = 1 ; (0,1)
x = 1, y = | 1-1| = 0 ; (1,0)
x = 2, y = |2-1| = 1 ; (2,1)
x = 3, y = |3-1| =2 ; (3, 2)
terlihat bahwa y =
4-3-2-1-0-1-2
jadi grafik turun lalu naik.
x = 1, y = 0 adalah TITIK BALIK.
