limit as x approaches infinity of x^2e^x

x \to \infty lim (x^{2} e^{x})

\infty

Solution steps

x \to \infty lim (x^{2} e^{x})

x \to a lim [f (x) \cdot g (x)] = x \to a lim f (x) \cdot x \to a lim g (x)

With the exception of indeterminate form

= x \to \infty lim (x^{2}) \cdot x \to \infty lim (e^{x})

x \to \infty lim (x^{2}) = \infty

x \to \infty lim (e^{x}) = \infty

= \infty \cdot \infty

Apply Infinity Property:

\infty \infty = \infty

= \infty

\frac{2}{s ( s ^{2} + 15 s + 50 )}

\int x ln (y + 1) d y

n = 0 \sum \infty (\frac{A}{A + 1})^{n}

f (x) = e^{9 x}
