domain of x/(x^2+6x+5)

domain

\frac{x}{x ^{2} + 6 x + 5}

x < - 5 or - 5 < x < - 1 or x > - 1

Interval Notation

(- \infty, - 5) \cup (- 5, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1, x = - 5

The function domain

x < - 5 or - 5 < x < - 1 or x > - 1

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

x^{3} + 1

f (x) = \frac{( \frac{x}{x + 3} )}{( \frac{x}{x + 3} ) + 3}

f (x) = 3 cot (\frac{1}{2} x) - 2

- (2)^{x} + 3

What is the domain of x/(x^2+6x+5) ?
The domain of x/(x^2+6x+5) is x<-5\lor-5<x<-1\lor x>-1
