domain of f(x)=(x^3+1)/x

domain

f (x) = \frac{x ^{3} + 1}{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

x^{4} - 256

f (x) = \frac{lo g _{10} ( x )}{1 - x}

f (x) = \frac{1}{2 x ^{2} + x}

f (x) = 2 x^{2} + 5

f (x) = lo g_{3} (2 x - 1) - 2

What is the domain of f(x)=(x^3+1)/x ?
The domain of f(x)=(x^3+1)/x is x<0\lor x>0
