domain of 1/(x^2+2x+1)

domain

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

f (x) = \frac{x ^{2} + 2}{8}

f (x) = e^{x^{2} - 1}

9 x^{4} - 36 x^{3} + 20 x^{2} + 32 x - 33

(8, 4), (22, 5)

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