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

domain

f (x) = \frac{( 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

y = - 3 2 x + 6 + 7

ln (X)

\frac{x ^{2} - 6 x + 4}{7}

(- 5 y)^{3}

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

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