domain of x^3+x^2-x-1

domain

x^{3} + x^{2} - x - 1

- \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

f (x) = 4 - 3 x

\frac{x}{9 + x ^{2}}

x - x^{3}

f (x) = \frac{x + 2}{6 - x}

4 x + 8
