domain of f(x)=(x-1)/(x^2+2x+1)

domain

f (x) = \frac{x - 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) = π (x)^{2}

f (x) = \frac{13 x + 7}{7 x - 4}

f (x) = x^{4} - 8 x^{2} + 5

y = 5

f (x) = \frac{( x - 1 )}{x + 1}

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