domain of (x/(x+1))/(x/(x+1)+1)

domain

\frac{\frac{x}{x + 1}}{\frac{x}{x + 1} + 1}

x < - 1 or - 1 < x < - \frac{1}{2} or x > - \frac{1}{2}

Interval Notation

(- \infty, - 1) \cup (- 1, - \frac{1}{2}) \cup (- \frac{1}{2}, \infty)

Solution steps

Find undefined (singularity) points:

x = - \frac{1}{2}, x = - 1

The function domain

x < - 1 or - 1 < x < - \frac{1}{2} or x > - \frac{1}{2}

y = 8 x - 5

f (x) = 5 x + 2

f (x) = 8 + 7 x

f (x) = 4 - x + x^{2} - 1

f (x) = x^{2} + 2, x \geq 0

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