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

domain

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

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) = 4 x + 20

f (x) = 4 x - 5

f (x) = (x + 2)^{2}

\frac{3 x ^{2} + 6}{x ^{2} - 2 x - 3}

x + 3 y = - 18

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