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

domain

f (x) = \frac{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) = - \frac{3}{4} x - \frac{11}{4}

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

x + 4 y = 0

f (x) = \frac{( 1 + x ^{4} )}{x ^{2} - x ^{4}}

2 x - 4 y = 8

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