domain of x^3-2

domain

x^{3} - 2

- \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

a sy m pt o t es 3 - 2 x - x^{2}

a sy m pt o t es f (x) = \frac{9 x ^{2} + 36 x + 41}{3 x + 5}

in v erse f (x) = (x - 15)^{2}, x \leq 15

d o main f (x) = 20 x^{3}

in v erse f (x) = \frac{3 x - 5}{x + 1}
