domain of f(x)= 1/(x+4)

domain

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

x < - 4 or x > - 4

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

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

f (x) = \frac{2 x + 1}{x - 5}

f (x) = x^{2} + 2 x + 7

7 tan (0.4 x)

y = - x - 7, (10, 8)

What is the domain of f(x)= 1/(x+4) ?
The domain of f(x)= 1/(x+4) is x<-4\lor x>-4
