limit as x approaches infinity of 7x^2+3x^3

x \to \infty lim (7 x^{2} + 3 x^{3})

\infty

Solution steps

x \to \infty lim (7 x^{2} + 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

16 x, at x = 16

(5, 0), (8, 15)

\frac{\partial}{\partial x} (\frac{y ^{2}}{( x + y ) ^{2}})

\int \frac{y}{( 4 + y ^{2} )} d y

\frac{d}{d x} (lo g_{3} ((x^{2} + 2 x)^{4}))
