limit as x approaches infinity of-2x-1

x \to \infty lim (- 2 x - 1)

- \infty

Solution steps

x \to \infty lim (- 2 x - 1)

Apply Infinity Property:

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

n is odd

a = - 2, n = 1

= - \infty

4 x, x^{2}

\int (2 y + 1) d y

\int_{3}^{9} \frac{1}{x ln ( x )} d x

y = 2 x + 1, at x = \frac{1}{2}

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