domain of f(x)=(x+11-5sqrt(5))/(x+1)

domain

f (x) = \frac{x + 11 - 5 5}{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

x^{2} + 10 x + 9

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

f (x) = \frac{x - 1}{x ( x ^{2} - 2 x - 15 )}

\frac{x ^{2} + x - 6}{( x + 8 ) ( x ^{2} - x - 2 )}

3 x^{4} + 4 x^{3} - 12 x^{2}

What is the domain of f(x)=(x+11-5sqrt(5))/(x+1) ?
The domain of f(x)=(x+11-5sqrt(5))/(x+1) is x<-1\lor x>-1
