Lim x -> -2 , x^3 + 8 / x+2 …. JAWAB DENGAN BENAR DAN TEPAT JANGAN ASAL JAWAB
GalladeavieroCara 1: Lim x -> -2 of (x³ + 8) / (x + 2) = Lim x -> -2 of (x³ + 2³) / (x + 2) = Lim x -> -2 of (x + 2)(x² - 2x + 4) / (x + 2) = Lim x -> -2 of (x² - 2x + 4) = (-2)² - 2(-2) + 4 = 4 + 4 + 4 = 12
Cara 2: Gunakan turunan: Lim x -> -2 of (x³ + 8) / (x + 2) = Lim x -> -2 of 3x² / 1 = 3(-2)² / 1 = 12

Kita masukkan nilai -2 ke fungsinya, maka akan menghasilkan nilai 0/0, maka kita harus faktorkan pembilangnya agar bisa kita sederhanakan. Gunakan cara horner, maka akan didapat:
Lim x -> -2 of (x³ + 8) / (x + 2)
= Lim x -> -2 of (x³ + 2³) / (x + 2)
= Lim x -> -2 of (x + 2)(x² - 2x + 4) / (x + 2)
= Lim x -> -2 of (x² - 2x + 4)
= (-2)² - 2(-2) + 4
= 4 + 4 + 4
= 12
Cara 2:
Gunakan turunan:
Lim x -> -2 of (x³ + 8) / (x + 2)
= Lim x -> -2 of 3x² / 1
= 3(-2)² / 1
= 12
Semoga Membantu ^^
