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

domain

f (x) = \frac{( x - 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

ln (x + 1) - 1

1 - (x^{2} - 1)^{2}

f (x) = \frac{x}{ln ( - x + 3 )}

f (x) = ln (5 - 4 x - x^{2}) + ln (- x)

f (x) = \frac{( x ^{2} - 3 x - 4 )}{x - 4}

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