domain of x^3-1

domain

x^{3} - 1

- \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

r an g e lo g_{2} (x) + 8

d o main f (x) = 5 - 15 x

in v erse 4 x - 8

e x t re m e f (x) = x^{3} - 3 x + 5

r an g e f (x) = 2 x + 6 + 2
