domain of f(x)= 3/(x+5)

domain

f (x) = \frac{3}{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) = x + 10

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

g (x) = \frac{x + 4}{x ^{2} - 9}

y = x^{2} - 4 x - 5

y = 2 x^{2} - 8 x + 8

What is the domain of f(x)= 3/(x+5) ?
The domain of f(x)= 3/(x+5) is x<-5\lor x>-5
