limit as x approaches infinity of x^2+4x

x \to \infty lim (x^{2} + 4 x)

\infty

Solution steps

x \to \infty lim (x^{2} + 4 x)

Apply Infinity Property:

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

n is even

a = 1, n = 2

= \infty

(x (ln (x))^{2})^{^{'}}

\int \frac{1}{( ρ ^{2} + z ^{2} ) ^{\frac{3}{2}}} d z

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

sin (y) \frac{d y}{d x} - cos (y) = 0

\frac{d}{d x} (\frac{x - 3}{2})
