Yang no 5 Tolong dijawab mau dikumpul...

Jawaban : b

f : x ⇒ x² - 1.
D = {x | -3 ≤ x ≤ 4, x ∈ bulat}.

f (-3) = (-3)² - 1 = 9-1 = 8.
f (-2)= (-2)² - 1 = 4-1 = 3.
f (-1)= (-1)² - 1 = 1-1= 0.
f (0)= (0)² - 1 = 0-1 = -1.
f (1)= (1)² - 1 = 1-1= 0.
f (2)= (2)² - 1 = 4-1 = 3.
f (3) = (3)² - 1 = 9-1 = 8.
f (4)= (4)² - 1 = 16-1 = 15.
