titik potong sumbu x
y = 0
x² - x - 12 = 0
(x - 4)(x + 3) = 0
x - 4 = 0
x = 4
x + 3 = 0
x = -3
Jadi kurva akan memotong sumbu x di x = 4 dan x = -3
titik potong sumbu y
x = 0
f (x) = (0)² - (0) - 12
f (x) = -12
y = -12
jadi kurva akan memotong sumbu y di y = -12
titik balik puncak
titik puncak x = -b / 2a
= -(-1) / 2.1
= 1/2
x = 1/2
titik balik puncak y :
f (1/2) = (1/2)² - 1/2 - 12
= 1/4 - 1/2 - 12
= 1/4 - 2/4 - 48/4
= -49/4
= -12 1/4
Jadi titik puncak baliknya = (1/2 , -12 1/4)
