domain of f(x)=(2x^2-x-6)/(x^2+9)

domain

f (x) = \frac{2 x ^{2} - x - 6}{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

\frac{x ^{12}}{x ^{- 2}}

x^{3} (x + 5)^{2} + 5

cos (5 x)

4 x + 5

15 x^{3} - 14
