Question

lim x → INFINITO = (7X² - 5X³+2) / (2+X²)

Answer 1

$\lim_{x \to \infty} \frac{7x^2-5x^3+2}{2+x^2}\\\\ \lim_{x \to \infty} \frac{x^3(\frac{7}{x}-5+\frac{2}{x^3})}{x^3(\frac{2}{x^3}+\frac{1}{x})}\\\\ \lim_{x \to \infty} \frac{\frac{7}{x}-5+\frac{2}{x^3}}{\frac{2}{x^3}+\frac{1}{x}}\\\\ \lim_{x \to \infty} \frac{0-5+0}{0+0}=-\infty$
