domain of x^2-2x-2

domain

x^{2} - 2 x - 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

e x t re m e f (x) = (x - 3)^{\frac{2}{3}}

d o main f (x) = \frac{( 3 x + 8 )}{x ^{2} - 81}

mi d p o in t (1, 2), (6, - 3)

r an g e f (x) = - x^{2} + 10 x - 24

a sy m pt o t es f (x) = 2^{- x}
