limit as x approaches infinity of 3x^3

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

\infty

Solution steps

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

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

y^{^{''}} - 3 y^{^{'}} + 2 y = 2 e^{t}, y (0) = 0, y^{^{'}} (0) = 0

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

\int e^{l n (x^{2})} d x

\int sec^{2} (5 x) tan^{6} (5 x) d x

f (x) = x^{2} - 49 x - 456, at x = 2
