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

domain

f (x) = \frac{9 - x}{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

g (x) = \frac{3 x + ∣ x ∣}{x}

f (x) = ln (3 - 8 x)

\frac{x ^{2}}{2 x - 5}

f (x) = \frac{1}{t ^{2} - 1}

arcsin (2 x - 3)

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