limit as x approaches infinity of x+x^3

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

\infty

Solution steps

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

Apply Infinity Property:

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

n is odd

a = 1, n = 3

= \infty

\int e^{- s^{2}} d s

h \to 0 lim (\frac{2. 7 ^{h} - 1}{h})

\frac{\partial}{\partial x} (\frac{y}{t})

\int \frac{1}{- x ^{2} + 12 x - 32} d x

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