Jawabpembuat nol fungsi , y = 0
y = (x - 1)² - 4
y = 0
(x -1)² - 4= 0
(x -1)² = 4
x - 1 = √4
x - 1 = 2 atau x - 1 = - 2
x = 3 atau x = - 1
Verified answer
JawabPembuat nol artinya y = f(x) = 0
y = 0
(x - 1)² - 4 = 0
(x - 1)² = 4
x - 1 = 2 atau x - 1 = -2
x = 3 atau x = -1
Jadi, pembuat nol fungsi adalah -1 dan 3
