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

domain

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

g (x) = - x

f (x) = - x + 14

f (x) = (\frac{7 x + 6}{7 x - 2})^{3 x - 1}

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

f (x) = x + 3 - x

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