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

domain

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

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

\frac{3 x}{x + 2}

4 sin (x)

f (x) = x - 4 + 3

y - 2 x = - 5

f (x) = \frac{x ^{3}}{9 - x}

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