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

\frac{d}{d x} (e^{3 x})

x \to 1 lim (3 1 - x)

\frac{( 12 x - 7 )}{3 x - 9}

f (x) = ln (3 x + 5)

f (x) = \frac{2 x}{x ^{2} + 2}
