domain of (x^2-4)^{2/3}

domain

(x^{2} - 4)^{\frac{2}{3}}

- \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

\frac{1 - x}{x ^{2} - 1}

f (x) = \frac{x - 1}{x ^{2} - 81}

(x - 1)^{2}

f (r) = \frac{2}{r ^{2} + 1}

f (x) = \frac{2 x + 1}{5 - x}
