domain of 2x^2-5

domain

2 x^{2} - 5

- \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) = 5 x - 15 x^{\frac{1}{3}}

\frac{x - 4}{x ^{2} - 16}

f (x) = \frac{- 5 x - 6}{- 15 x - 28}

\frac{1}{x - 2}

\frac{x - 3}{x - 6}
