(- \infty, \infty)

Solution steps

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

- \infty < x < \infty

a sy m pt o t es f (x) = x 4 - x

in t erce pt s f (x) = (x + 1)^{2} - 36

in t erce pt s - 2 x^{3} + 18 x^{2} + 168 x - 4

in v erse f (x) = \frac{1}{2 x + 1}
