Answer to Question #188351 in Calculus for Maureen

Question

Evaluate the limits

$Lim$

Xto + sum to infinity

5xcube-2xsquared +1 divide by 1-3x

Answer 1

We need to find,

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

The highest power of the x is 3.

When we find $\lim_{x \to \infty}$ we need to find the ratio of the coefficients of the highest power in numerator and denominator.

Here, $\lim_{x \to \infty} \frac{5x^3-2x^2}{1-3x} = \frac{5}{0 } = \infty$
