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

domain

g (x) = \frac{2}{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

\frac{1}{4 9 - x ^{2}}

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

f (x) = 200 - \frac{x}{30}

f (x) = - \frac{2}{x ^{2} + 2 x - 35}

f (x) = 2 x + 3, x \geq - 4

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