domain of f(x)=(x^3)/3-9x

domain

f (x) = \frac{x ^{3}}{3} - 9 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

f (x) = \frac{1}{2.1 x - 6 x ^{2}}

\frac{5 x + 2}{x - 9}

3 x^{2} - 4 x + 7

- \frac{3}{4} x + 2

f (x) = \frac{x - 6}{x ^{2} + 25}
