domain of (x^2-7x-8)/(x+1)

domain

\frac{x ^{2} - 7 x - 8}{x + 1}

x < - 1 or x > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

f (x) = - 8 a x + 1

f (x) = \frac{7 x}{6 x - 5}

f (x) = g (x) = - 3

- 5 - x

- 2 + 4 cos (x)

What is the domain of (x^2-7x-8)/(x+1) ?
The domain of (x^2-7x-8)/(x+1) is x<-1\lor x>-1
