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

domain

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

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}

\frac{2 x + 3}{4}

f (x) = \frac{3 x - 1}{2 x + 5}

f (x) = (\frac{4}{x}) (\frac{6}{x + 6})

f (x) = \frac{2 - x}{x ^{2} - 1}

(2.6) y = - 3 x + 7

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