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

domain

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

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - \frac{1}{2}

The function domain

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

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