domain of f(x)=(x-2)/(x^3+2x)

domain

f (x) = \frac{x - 2}{x ^{3} + 2 x}

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

sin (\frac{1}{x})

64 - x^{3}

- 3 X + Y - 157 = 0

f (x) = x^{3} - 2 x^{2} - 35 x

f (x) = \frac{x}{3 x - 1}

What is the domain of f(x)=(x-2)/(x^3+2x) ?
The domain of f(x)=(x-2)/(x^3+2x) is x<0\lor x>0
