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

domain

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

x < - 1 or x > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

f (x) = ln (5 t + 10)

f (x) = 3 \frac{y}{( ( y - 6 ) )}

f (x) = \frac{3 x + 4 x}{x ^{2} + 7 x + 12}

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

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

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