limit as x approaches-infinity of-3x

x \to - \infty lim (- 3 x)

\infty

Solution steps

x \to - \infty lim (- 3 x)

Apply Infinity Property:

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

n is odd

a = - 3, n = 1

= \infty

n = 1 \sum \infty \frac{10}{n}

x \to 0 lim (\frac{tan ( 0 )}{0})

\frac{1}{x + 7}

\frac{d}{d x} (\frac{x}{7 x + 9})

\int 0.2 t^{2} d t
