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

domain

f (x) = \frac{2 x}{x ^{2} + 2 x + 1}

x < - 1 or x > - 1

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

(x - 1)^{2} - 4

f (x) = \frac{3 x - 1}{2 x + 8}

f (x) = 5 x^{2} - 1

\frac{1}{x ^{2} + 2 x + 2}, - 2 \leq x \leq 2

3 x - 10 y = 20

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