domain of f(x)=(3x^3+5)/(1-x^3)

domain

f (x) = \frac{3 x ^{3} + 5}{1 - x ^{3}}

x < 1 or x > 1

Interval Notation

(- \infty, 1) \cup (1, \infty)

Solution steps

Find undefined (singularity) points:

x = 1

The function domain

x < 1 or x > 1

\frac{x ^{\frac{1}{2}}}{( x - 3 )}

- 0.015 x^{2} + 1.22 x - 7.2

f (x) = ln (x^{2} - 8 x + 15)

f (x) = - 3 x + 1 - 4 x + 5

f (x) = \frac{3 x}{x - 7}

What is the domain of f(x)=(3x^3+5)/(1-x^3) ?
The domain of f(x)=(3x^3+5)/(1-x^3) is x<1\lor x>1
