domain of f(x)=(x-9)/(x^2+64)

domain

f (x) = \frac{x - 9}{x ^{2} + 64}

- \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) = - 2 x + 5 - 3

\frac{6}{x ( x + 9 )}

\frac{x - 7}{5 x - 1}

4 x - 8

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