Tentukan nilai limit fungsi berikut: [tex]\lim_{x \to \infty} (x- \sqrt{x^2+9x+1})[/tex]

Kelas 11 Matematika
Bab Limit 

lim (x - √(x² + 9x + 1))
x→∞

= lim (√x² - √(x² + 9x + 1))
   x→ ∞

a = 1; b = 0; c = 0; p = 1; q = 9; r = 1

Karena a = p = 1, maka

(b - q)/(2√a)
= (0 - 9)/(2√1)
= -9/2
= -4 1/2
