domain of (x^2+2x-8)/(x+4)

domain

\frac{x ^{2} + 2 x - 8}{x + 4}

x < - 4 or x > - 4

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

f (x) = \frac{x - 3}{x - 4}

y = sec (x^{2} + 3 x)

y = x + \frac{1}{x + 5}

f (x) = x^{2} + 9

\frac{3 x - 2}{x + 5}

What is the domain of (x^2+2x-8)/(x+4) ?
The domain of (x^2+2x-8)/(x+4) is x<-4\lor x>-4
