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

domain

y = \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

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

f (x) = 2 x

\frac{x ^{2} + 2 x - 15}{x ^{2} + 7 x + 10}

f (x) = x - 3 x - 1

f (x) = \frac{1}{25 - t}

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