domain of f(x)=(x+9)/(x^2+2x+1)

domain

f (x) = \frac{x + 9}{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

\frac{5 x}{3 x - 8}

f (x) = lo g_{4} (x + 6)

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

f (x) = \frac{5 x ^{2} - x}{2 x}

- 7 x + 4

What is the domain of f(x)=(x+9)/(x^2+2x+1) ?
The domain of f(x)=(x+9)/(x^2+2x+1) is x<-1\lor x>-1
