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

domain

\frac{2 x - 2}{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

f (x) = 3 x - x^{3}

y = 5 x - 5

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

\frac{1}{6} x^{4} + 2 x^{3} + 9 x^{2}

\frac{x - 2}{1 - 3 x}

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