domain of 1/(x^3+4x)

Solution

domain

\frac{1}{x ^{3} + 4 x}

Solution

x < 0 or x > 0

+1

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

Popular Examples

range of y= x/(x^2+x-6)range

y = \frac{x}{x ^{2} + x - 6}

inflection f(x)=x^3-6x^2-36x inflection points

f (x) = x^{3} - 6 x^{2} - 36 x

intercepts of f(x)=y^2-x-25=0 intercepts

f (x) = y^{2} - x - 25 = 0

asymptotes of e^{-x}+4 asymptotes

e^{- x} + 4

parity (4x^2-5)/(2x^3+x)parity

\frac{4 x ^{2} - 5}{2 x ^{3} + x}
