Question

o valor do lim 2x2 -5x +1/ 4x2 +3x -7 é:
x-8 deitado

Answer 1

$\lim_{x \to \infty} \frac{2x^2 -5x +1}{4x^2 +3x -7}$

$\lim_{x \to \infty} \frac{2 -\frac5x +\frac{1}{x^2}}{4 +\frac{3}{x} -\frac{7}{x^2}}$

$\frac{2 -\frac{5}{\infty} +\frac{1}{\infty}}{4 +\frac{3}{\infty} -\frac{7}{\infty}}$

$\frac{2 -0 +0}{4 +0-0}$

$\frac{2}{4}$

$\frac12$

Answer 2

A RESPOSTA CORRETA É : 1/2
