domain of (x-4)/(x^2+9)

domain

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

- \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

tan (t)

\frac{x}{7 x - 2}

f (x) = \frac{4}{x + 7}

f (x) = \frac{6}{x + 1}

f (x) = \frac{3 x + 5}{x ^{2} - x - 30}
