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

domain

f (x) = x^{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

2 x^{2} - 3 x - 2

f (x) = \frac{8 - x ^{2}}{3}

y = 8

f (x) = 20 x

f (x) = ∣ x ∣ + ∣ x - 1 ∣

What is the domain of f(x)=x^3-9x ?
The domain of f(x)=x^3-9x is -infinity <x<infinity
