limit as x approaches-infinity of x^3+x

x \to - \infty lim (x^{3} + x)

- \infty

Solution steps

x \to - \infty lim (x^{3} + x)

Apply Infinity Property:

x \to - \infty lim (a x^{n} + \dots + b x + c) = - \infty, a > 0,

n is odd

a = 1, n = 3

= - \infty

\frac{d}{d x} (\frac{tan ( x )}{cos ( x ) - 4})

n = 1 \sum \infty - \frac{5}{2 ^{n - 1}}

x \to \infty lim (3)

\int (x + π) d x

F (s) = \frac{( s + 2 ) ^{2}}{s ^{3}}
