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

domain

f (x) = \frac{13}{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

x^{3} + 2 x^{2} - 5 x - 4

x^{3} + 2 x^{2} - 5 x - 6

f (x) = 4 \cdot 3 x + 4

f (x) = \frac{1}{4} x + 40

f (x) = x^{4} - 8 x^{2} + 13

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