limit as x approaches-infinity of x^2+2x

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

\infty

Solution steps

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

Apply Infinity Property:

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

n is even

a = 1, n = 2

= \infty

\frac{d ^{2} x}{d x ^{2}}

\frac{d}{d x} (- \frac{15 x ^{4}}{2} + \frac{6 x ^{2}}{5} - \frac{x}{3} - 4)

\int x cos^{3} (x) d x

x \to 0 lim (\frac{ln ( 1 + \frac{1}{x} )}{x})

\frac{d}{d x} (\frac{x}{( 1 - 2 x ) ^{2}})
