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

domain

y = \frac{x - 1}{x + 2}

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

9 - 6 x

f (x) = \frac{x - 3}{\frac{1}{x}}

f (x) = - 3 x - 2 - 4

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

\frac{x ^{4}}{x ^{2} + x - 30}

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