Answer 1

Jawaban:

limit tak hingga

lim x→∞ a/xⁿ = 0

maka:

lim x→∞ (x²-2x-1)/(3x²+6x-1) → bagi dgn variabel pangkat tertinggi yaitu x²

= (x²/x² - 2x/x² - 1/x²)/(3x²/x² +6x/x² -1/x²)

= (1 - 2/x - 1/x²)/(3 +6/x - 1/x²)

= (1-0-0)/(3+0-0)

= 1/3

Answer 2

Verified answer

limit tak hingga

lim x→∞ (x² - 2x - 1)/(3x² + 6x - 1)

= lim x→∞ x²(1 - 2/x - 1/x²) / x²(3 + 6/x - 1/x²)

= lim x→∞ (1 - 2/x - 1/x²) / (3 + 6/x - 1/x²)

= (1 - 2/∞ - 1/∞) / (3 + 6/∞ - 1/∞)

= (1 - 0 - 0)/(3 + 0 - 0)

= 1/3

atau

cara pada lampiran

derajat sama

lihat koefisien

lim x→∞ (1x² - 2x - 1)/(3x² + 6x - 1)

= 1/3
