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

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

\infty

Solution steps

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

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

\int_{1}^{2} 3 x^{2} d x

\int \frac{1}{x ^{2} + 4 x + 3} d x

\int_{2}^{4} - x^{2} + 6 x - 8 d x

x \to - 8 - lim (\frac{x + 7}{x + 8})

cos (\frac{x}{2})
