Pregunta: Calculate the limit. Show all necessary work. limx→∞3x2+4x+15+6x+7x2

Divide the numerator and denominator by the highest power of $\mathrm{x}$ in the denominator, which is ${\mathrm{x}}^2$ .

$\underset{\mathrm{x}\to \mathrm{\infty }}{lim}\left(\frac{\frac{3{\mathrm{x}}^2}{{\mathrm{x}}^2}+\frac{4\mathrm{x}}{{\mathrm{x}}^2}+\frac{1}{{\mathrm{x}}^2}}{\frac{5}{{\mathrm{x}}^2}+\frac{6\mathrm{x}}{{\mathrm{x}}^2}+\frac{7{\mathrm{x}}^2}{{\mathrm{x}}^2}}\right)$
