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

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

\infty

Solution steps

x \to - \infty lim (- 3 x^{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 = 3

= \infty

f (x) = 2 x^{2}, at x = 1

\int 5 x^{3} + 3 x + 7 d x

\frac{d}{d t} (a cos (t))

x \to 0 lim (- \frac{ln ( 1 + 6 x )}{x})

\int (4 x^{6} - 2 x^{3} + 7 x - 4) d x
