domain of 2/(x+1)

Solution

domain

\frac{2}{x + 1}

Solution

x < - 1 or x > - 1

+1

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

Popular Examples

extreme f(x)=2x^3+3x^2-12x+5 extreme points

f (x) = 2 x^{3} + 3 x^{2} - 12 x + 5

asymptotes of f(x)=(x+4)/(x+2)asymptotes

f (x) = \frac{x + 4}{x + 2}

domain of f(y)=6x+8y=-10 domain

f (y) = 6 x + 8 y = - 10

parity x-tan(x)parity

x - tan (x)

domain of f(x)=ln(x+2)domain

f (x) = ln (x + 2)
