Pregunta: limx→-∞-2x3+x2+4x-4-2x3-2x2-7x-7

Divide the numerator and denominator by the highest power of $\mathrm{x}$ in the denominator, which is ${\mathrm{x}}^3$ .

$\underset{\mathrm{x}\to -\mathrm{\infty }}{lim}\left(\frac{\frac{-2{\mathrm{x}}^3}{{\mathrm{x}}^3}+\frac{{\mathrm{x}}^2}{{\mathrm{x}}^3}+\frac{4\mathrm{x}}{{\mathrm{x}}^3}+\frac{-4}{{\mathrm{x}}^3}}{\frac{-2{\mathrm{x}}^3}{{\mathrm{x}}^3}+\frac{-2{\mathrm{x}}^2}{{\mathrm{x}}^3}+\frac{-7\mathrm{x}}{{\mathrm{x}}^3}+\frac{-7}{{\mathrm{x}}^3}}\right)$
