domain of (x^2+2x-8)/(x+2)

domain

\frac{x ^{2} + 2 x - 8}{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) = \frac{1}{x ^{2} + 5}

\frac{3 x}{x + 6}

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

f (x) = - 2 sec (\frac{x}{2}) + 3

f (x) = x - 2 + 4

What is the domain of (x^2+2x-8)/(x+2) ?
The domain of (x^2+2x-8)/(x+2) is x<-2\lor x>-2
