domain of f(x)= 2/(x+4)

domain

f (x) = \frac{2}{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

f (x) = x^{7} + 1

f (x) = \frac{1}{2} y^{2} - 1

7 x^{2} - 2

16 - x^{2}

y = \frac{7}{8} x - 7

What is the domain of f(x)= 2/(x+4) ?
The domain of f(x)= 2/(x+4) is x<-4\lor x>-4
