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

domain

\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

f (x) = - 5 x - 42 x^{2} - 4

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

\frac{x ^{2} - 3 x - 4}{x + 2}

- x^{2} + 9

- 10 (x + 9)^{4} (x - 4)^{4}

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