domain of (x^2+6)/3

domain

\frac{x ^{2} + 6}{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{3 x}{x - 10}

\frac{3 x + 3}{x ^{2} - 49}

f (x) = - \frac{4}{x}

x = y^{3}

y = x^{5}
