Pregunta: Find limx→∞x2-9x-8x3-1

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

$\underset{\mathrm{x}\to \mathrm{\infty }}{lim}\left(\frac{\frac{{\mathrm{x}}^2}{{\mathrm{x}}^3}+\frac{-9\mathrm{x}}{{\mathrm{x}}^3}+\frac{-8}{{\mathrm{x}}^3}}{\frac{{\mathrm{x}}^3}{{\mathrm{x}}^3}-\frac{1}{{\mathrm{x}}^3}}\right)$
