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

\int \frac{4 x + 13}{x ^{2} + 3 x - 10} d x

\frac{\partial}{\partial x} (2 x^{2} y + 2 x)

\int_{0}^{1} x e^{- 2 x^{2}} d x

(- 29) (- 2 - 5)

x \to - \infty lim (3 x^{6})
