limit as x approaches infinity of 2x^3-1

x \to \infty lim (2 x^{3} - 1)

\infty

Solution steps

x \to \infty lim (2 x^{3} - 1)

Apply Infinity Property:

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

n is odd

a = 2, n = 3

= \infty

\frac{d y}{d x} = \frac{( 1 + x y )}{1 + x}

\frac{x}{x + 9}

\int (e^{2 x} + 3)^{4} \cdot e^{2 x} d x

y^{^{''}} + 121 y = cos (4 t)

\frac{d}{d x} (9 e^{x} + \frac{8}{3 x})
