domain of f(x)= 1/(2+x)

domain

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

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

8 - 3 e^{x}

(2 - x) e^{- x} - 1

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

(3 - 4) m = - 4

f (x) = \frac{x ^{2} - 9}{x + 3}

What is the domain of f(x)= 1/(2+x) ?
The domain of f(x)= 1/(2+x) is x<-2\lor x>-2
