domain of f(x)= 5/(x+9)

domain

f (x) = \frac{5}{x + 9}

x < - 9 or x > - 9

Interval Notation

(- \infty, - 9) \cup (- 9, \infty)

Solution steps

Find undefined (singularity) points:

x = - 9

The function domain

x < - 9 or x > - 9

f (x) = ln (4 - x^{3})

ln (0)

\frac{3 x + 21}{6 x + 6}

f (x) = \frac{4 x - 5}{5 x - 20}

f (x) = \frac{t - 5}{2 t - 16}

What is the domain of f(x)= 5/(x+9) ?
The domain of f(x)= 5/(x+9) is x<-9\lor x>-9
