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

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

\infty

Solution steps

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

Apply Infinity Property:

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

n is even

a = 2, n = 2

= \infty

y^{^{'}} = y (x y^{3} + 1)

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

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

14 (2 e^{x^{2}} x^{2} + e^{x^{2}})

\frac{d}{d z} (x y e^{(x^{2} + z^{2} - 5)})
