domain of f(x)= 3/(x+13)

domain

f (x) = \frac{3}{x + 13}

x < - 13 or x > - 13

Interval Notation

(- \infty, - 13) \cup (- 13, \infty)

Solution steps

Find undefined (singularity) points:

x = - 13

The function domain

x < - 13 or x > - 13

f (x) = - 5^{x}

f (x) = x^{2} + 4 x + 6

y = - 3 x + 2

f (x) = \frac{x + 8}{x ^{2} ( 5 - 2 x ) ^{3}}

What is the domain of f(x)= 3/(x+13) ?
The domain of f(x)= 3/(x+13) is x<-13\lor x>-13
