domain of f(x)=x^3-2x+9

domain

f (x) = x^{3} - 2 x + 9

- \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

x - 9

(- 10.4) (8.8)

y = 4 t^{2}

y = - \frac{2}{3} x - \frac{1}{3}

f (x) = \frac{27 x}{x ^{2} + 9}
