domain of f(x)=x^{(2/3)}

domain

f (x) = 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

y = x^{3} - 1

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

f (x) = \frac{3 x ^{2} + 6 x + 9}{x + 9}

- 7 x + 7

f (x) = arctan (\frac{x ^{2}}{x + 5})
