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

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

\infty

Solution steps

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

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

x \to 0 lim (\frac{- 1}{∣ x ∣})

x \to 0 lim ((1 + 2 x)^{\frac{2}{x}})

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

x \to 0 lim ((x + 2^{x})^{\frac{2}{x}})

x \to 2 lim (- \frac{2}{( x - 2 ) ^{2}})
