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

domain

f (x) = \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

f (x) = \frac{x ^{2}}{3}

\frac{2 x + 3}{3 x - 4}

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

2 + ln (x)

lo g_{10} (x - 5) + 1
