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

domain

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

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

2 x^{3} - 3 x^{2} - 12 x + 8

\frac{2 x + 14}{x ^{2} - 49}

\frac{1}{6 - 2 x - x ^{2}}

\frac{3 x}{5 x - 6}

\frac{6}{x ^{2} - 4}
