domain of 2/(\frac{x){x+2}}

domain

\frac{2}{\frac{x}{x + 2}}

x < - 2 or - 2 < x < 0 or x > 0

Interval Notation

(- \infty, - 2) \cup (- 2, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 2

The function domain

x < - 2 or - 2 < x < 0 or x > 0

f (x) = x^{2} + x - 12

y = - 0.23 x^{2} + 1.87 x + 1.5

f (x) = x e^{- 8 x}

y = y + 4, at 2, 2

f (x) = \frac{x + 8}{2 - x}

What is the domain of 2/(\frac{x){x+2}} ?
The domain of 2/(\frac{x){x+2}} is x<-2\lor-2<x<0\lor x>0
