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

domain

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

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

y = - 2 x - 1

\frac{1}{x ^{2} + 6 x + 9}

y = - 2 x - 2

f (x) = (x - 7)^{2} + (y - 1)^{2} = 4

t^{2} - 4 t + 2

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