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

domain

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

x < - 5 or x > - 5

Interval Notation

(- \infty, - 5) \cup (- 5, \infty)

Solution steps

Find undefined (singularity) points:

x = - 5

The function domain

x < - 5 or x > - 5

f (x) = \frac{x ^{2}}{x ^{4} + 1}

f (x) = \frac{1}{e ^{x} + 1}

f (x) = (x - 1)^{2} - 2

\frac{1}{2 - x}

y = - \frac{7}{6} x + 10

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