domain of y=x^{2/3}

domain

y = x^{\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

f (x) = \frac{2 x - 7}{9 x + 2}

\frac{8 x ^{2} + 12 x}{9 x ^{2} - 12 x + 4}

\frac{- x ^{2} + 7 x - 10}{x - 3}

f (x) = 1 - \frac{x ^{2}}{16}

f (x) = \frac{1 - 3 x}{x ^{3} - 4 x ^{2} - 5 x}
